-====== old index for f2c, now "readme from f2c" ============
-
-FILES:
-
-f2c.h	Include file necessary for compiling output of the converter.
-	See the second NOTE below.
-
-f2c.1	Man page for f2c.
-
-f2c.1t	Source for f2c.1 (to be processed by troff -man or nroff -man).
-
-libf77	Library of non I/O support routines the generated C may need.
-	Fortran main programs result in a C function named MAIN__ that
-	is meant to be invoked by the main() in libf77.
-
-libi77	Library of Fortran I/O routines the generated C may need.
-	Note that some vendors (e.g., BSD, Sun and MIPS) provide a
-	libF77 and libI77 that are incompatible with f2c -- they
-	provide some differently named routines or routines with the
-	names that f2c expects, but with different calling sequences.
-	On such systems, the recommended procedure is to merge
-	libf77 and libi77 into a single library, say libf2c, and to
-        install it where you can access it by specifying -lf2c .  The
-        definition of link_msg in sysdep.c assumes this arrangement.
-
-	Both libf77 and libi77 are bundles, meant to be unpacked by the
-	Bourne (or Korn) shell.  MS-DOS users can use the MKS Toolkit
-	to unpack libf77 and libi77.
-
-libf2c.zip
-	Only available by ftp: combination of libf77 and libi77, with
-	Unix and PC makefiles.
-
-f2c.ps	Postscript for a technical report on f2c.  After you strip the
-	mail header, the first line should be "%!PS".
-
-fixes	The complete change log, reporting bug fixes and other changes.
-	(Some recent change-log entries are given below).
-
-fc	A shell script that uses f2c and imitates much of the behavior
-	of commonly found f77 commands.  You will almost certainly
-	need to adjust some of the shell-variable assignments to make
-	this script work on your system.
-
-
-SUBDIRECTORY:
-
-f2c/src	Source for the converter itself, including a file of checksums
-	and source for a program to compute the checksums (to verify
-	correct transmission of the source), is available: ask netlib
-	(e.g., netlib@netlib.bell-labs.com) to
-		send all from f2c/src
-	If the checksums show damage to just a few source files, or if
-	the change log file (see "fixes" below) reports corrections to
-	some source files, you can request those files individually
-	"from f2c/src".  For example, to get defs.h and xsum0.out, you
-	would ask netlib to
-		send defs.h xsum0.out from f2c/src
-	"all from f2c/src" is about 640 kilobytes long; for convenience
-	(and checksums), it includes copies of f2c.h, f2c.1, and f2c.1t.
-
-	Tip: if asked to send over 99,000 bytes in one request, netlib
-	breaks the shipment into 1000 line pieces and sends each piece
-	separately (since otherwise some mailers might gag).  To avoid
-	the hassle of reassembling the pieces, try to keep each request
-	under 99,000 bytes long.  The final number in each line of
-	xsum0.out gives the length of each file in f2c/src.  For
-	example,
-		send exec.c expr.c from f2c/src
-		send format.c format_data.c from f2c/src
-	will give you slightly less hassle than
-		send exec.c expr.c format.c format_data.c from f2c/src
-	Alternatively, if all the mailers in your return path allow
-	long messages, you can supply an appropriate mailsize line in
-	your netlib request, e.g.
-		mailsize 200k
-		send exec.c expr.c format.c format_data.c from f2c/src
-
-	The makefile used to generate gram.c; now we distribute a
-	working gram.c, and you must say
-		make gram1.c
-		mv gram1.c gram.c
-	if you want to generate your own gram.c -- there are just too
-	many broken variants of yacc floating around nowadays for
-	generation of gram.c to be the default.
-
-NOTE:	You may exercise f2c by sending netlib@netlib.bell-labs.com
-	a message whose first line is "execute f2c" and whose remaining
-	lines are the Fortran 77 source that you wish to have converted.
-	Return mail brings you the resulting C, with f2c's error
-	messages between #ifdef uNdEfInEd and #endif at the end.
-	(To understand line numbers in the error messages, regard
-	the "execute f2c" line as line 0.  It is stripped away by
-	the netlib software before f2c sees your Fortran input.)
-	Options described in the man page may be transmitted to
-	netlib by having the first line of input be a comment
-	whose first 6 characters are "c$f2c " and whose remaining
-	characters are the desired options, e.g., "c$f2c -R -u".
-
-	You may say "execute f2c" in the Subject line instead of (but
-	*not* in addition to) in the first line of the message body.
-
-	The incoming Fortran is saved, at least for a while.  Don't
-	send any secrets!
-
-
-BUGS:	Please send bug reports (including the shortest example
-	you can find that illustrates the bug) to research!dmg
-	or dmg@bell-labs.com .  You might first check whether
-	the bug goes away when you turn optimization off.
-
-
-NOTE:	f2c.h defines several types, e.g., real, integer, doublereal.
-	The definitions in f2c.h are suitable for most machines, but if
-	your machine has sizeof(double) > 2*sizeof(long), you may need
-	to adjust f2c.h appropriately.  f2c assumes
-		sizeof(doublecomplex) = 2*sizeof(doublereal)
-		sizeof(doublereal) = sizeof(complex)
-		sizeof(doublereal) = 2*sizeof(real)
-		sizeof(real) = sizeof(integer)
-		sizeof(real) = sizeof(logical)
-		sizeof(real) = 2*sizeof(shortint)
-	EQUIVALENCEs may not be translated correctly if these
-	assumptions are violated.
-
-	On machines, such as those using a DEC Alpha processor, on
-	which sizeof(short) == 2, sizeof(int) == sizeof(float) == 4,
-	and sizeof(long) == sizeof(double) == 8, it suffices to
-	modify f2c.h by removing the first occurrence of "long "
-	on each line containing "long ", e.g., by issuing the
-	commands
-		mv f2c.h f2c.h0
-		sed 's/long //' f2c.h0 >f2c.h
-	On such machines, one can enable INTEGER*8 by uncommenting
-	the typedef of longint in f2c.h, so it reads
-		typedef long longint;
-	by compiling libI77 with -DAllow_TYQUAD, and by adjusting
-	libF77/makefile as described in libF77/README.
-
-	Some machines may have sizeof(int) == 4, sizeof(float) == 8,
-	and sizeof(long long) == 8.  On such machines, adjust f2c.h
-	by changing "long int " to "long long ", e.g., by saying
-		mv f2c.h f2c.h0
-		sed 's/long int /long long /' f2c.h0 >f2c.h
-	One can enable INTEGER*8 on such machines as described
-	above, but with
-		typedef long long longint;
-
-	There exists a C compiler that objects to the lines
-		typedef VOID C_f;	/* complex function */
-		typedef VOID H_f;	/* character function */
-		typedef VOID Z_f;	/* double complex function */
-	in f2c.h .  If yours is such a compiler, do two things:
-	1. Complain to your vendor about this compiler bug.
-	2. Find the line
-		#define VOID void
-	   in f2c.h and change it to
-		#define VOID int
-	(For readability, the f2c.h lines shown above have had two
-	tabs inserted before their first character.)
-
-FTP:	All the material described above is now available by anonymous
-	ftp from netlib.bell-labs.com (login: anonymous; Password: your
-	E-mail address; cd netlib/f2c).  Note that you can say, e.g.,
-
-		cd /netlib/f2c/src
-		binary
-		prompt
-		mget *.gz
-
-	to get all the .gz files in src.  You must uncompress the .gz
-	files once you have a copy of them, e.g., by
-
-		gzip -dN *.gz
-
-	You can also get the entire f2c tree as a tar file:
-
-		ftp://netlib.bell-labs.com/netlib/f2c.tar
-
-	(which is a synthetic file -- created on the fly and not visible
-	to ftp's "ls" or "dir" commands).
-
-	Subdirectory msdos contains two PC versions of f2c,
-	f2c.exe.gz and f2cx.exe.gz; the latter uses extended memory.
-	The README in that directory provides more details.
-
-	Changes appear first in the f2c files available by E-mail
-	from netlib@netlib.bell-labs.com.  If the deamons work right,
-	changed files are available the next day by ftp from
-	netlib.bell-labs.com.  In due course, they reach other netlib servers.
-
-CHANGE NOTIFICATION:
-	Send the E-mail message
-		subscribe f2c
-	to netlib@netlib.bell-labs.com to request notification of new and
-	changed f2c files.  (Beware that automatically sent change
-	notifications may reach you before changes have reached
-	ftp://netlib.bell-labs.com/netlib/f2c or to other netlib servers.)
-	Send the E-mail message
-		unsubscribe f2c
-	to recant your notification request.

------------------
-Recent change log (partial)
------------------
-
-Mon May 13 23:35:26 EDT 1996
-  Recognize Fortran 90's /= as a synonym for .NE..  (<> remains a
-synonym for .NE..)
-  Emit an empty int function of no arguments to supply an external
-name to named block data subprograms (so they can be called somewhere
-to force them to be loaded from a library).
-  Fix bug (memory fault) in handling the following illegal Fortran:
-	parameter(i=1)
-	equivalence(i,j)
-	end
-  Treat cdabs, cdcos, cdexp, cdlog, cdsin, and cdsqrt as synonyms for
-the double complex intrinsics zabs, zcos, zexp, zlog, zsin, and zsqrt,
-respectively, unless -cd is specified.
-  Recognize the Fortran 90 bit-manipulation intrinsics btest, iand,
-ibclr, ibits, ibset, ieor, ior, ishft, and ishftc, unless -i90 is
-specified.  Note that iand, ieor, and ior are thus now synonyms for
-"and", "xor", and "or", respectively.
-  Add three macros (bit_test, bit_clear, bit_set) to f2c.h for use
-with btest, ibclr, and ibset, respectively.  Add new functions
-[lq]bit_bits, [lq]bit_shift, and [lq]_bit_cshift to libF77 for
-use with ibits, ishft, and ishftc, respectively.
-  Add integer function ftell(unit) (returning -1 on error) and
-subroutine fseek(unit, offset, whence, *) to libI77 (with branch to
-label * on error).
-
-Tue May 14 23:21:12 EDT 1996
-  Fix glitch (possible memory fault, or worse) in handling multiple
-entry points with names over 28 characters long.
-
-Mon Jun 10 01:20:16 EDT 1996
-  Update netlib E-mail and ftp addresses in f2c/readme and
-f2c/src/readme (which are different files) -- to reflect the upcoming
-breakup of AT&T.
-  libf77: trivial tweaks to F77_aloc.c and system_.c; Version.c not
-changed.
-  libi77: Adjust rsli.c and lread.c so internal list input with too
-few items in the input string will honor end= .
-
-Mon Jun 10 22:59:57 EDT 1996
-  Add Bits_per_Byte to sysdep.h and adjust definition of Table_size
-to depend on Bits_per_Byte (forcing Table_size to be a power of 2); in
-lex.c, change "comstart[c & 0xfff]" to "comstart[c & (Table_size-1)]"
-to avoid an out-of-range subscript on end-of-file.
-
-Wed Jun 12 00:24:28 EDT 1996
-  Fix bug in output.c (dereferencing a freed pointer) revealed in
-	print *		!np in out_call in output.c clobbered by free
-	end		!during out_expr.
-
-Wed Jun 19 08:12:47 EDT 1996
-  f2c.h: add types uinteger, ulongint (for libF77); add qbit_clear
-and qbit_set macros (in a commented-out section) for integer*8.
-  For integer*8, use qbit_clear and qbit_set for ibclr and ibset.
-  libf77: add casts to unsigned in [lq]bitshft.c.
-
-Thu Jun 20 13:30:43 EDT 1996
-  Complain at character*(*) in common (rather than faulting).
-  Fix bug in recognizing hex constants that start with "16#" (e.g.,
-16#1234abcd, which is a synonym for z'1234abcd').
-  Fix bugs in constant folding of expressions involving btest, ibclr,
-and ibset.
-  Fix bug in constant folding of rshift(16#80000000, -31) (on a 32-bit
-machine; more generally, the bug was in constant folding of
-rshift(ibset(0,NBITS-1), 1-NBITS) when f2c runs on a machine with
-long ints having NBITS bits.
-
-Mon Jun 24 07:58:53 EDT 1996
-  Adjust struct Literal and newlabel() function to accommodate huge
-source files (with more than 32767 newlabel() invocations).
-  Omit .c file when the .f file has a missing final end statement.
-
-Wed Jun 26 14:00:02 EDT 1996
-  libi77: Add discussion of MXUNIT (highest allowed Fortran unit number)
-to libI77/README.
-
-Fri Jun 28 14:16:11 EDT 1996
-  Fix glitch with -onetrip: the temporary variable used for nonconstant
-initial loop variable values was recycled too soon.  Example:
-	do i = j+1, k
-		call foo(i+1)	! temp for j+1 was reused here
-		enddo
-	end
-
-Tue Jul  2 16:11:27 EDT 1996
-  formatdata.c: add a 0 to the end of the basetype array (for TYBLANK)
-(an omission that was harmless on most machines).
-  expr.c: fix a dereference of NULL that was only possible with buggy
-input, such as
-	subroutine $sub(s)	! the '$' is erroneous
-	character s*(*)
-	s(1:) = ' '
-	end
-
-Sat Jul  6 00:44:56 EDT 1996
-  Fix glitch in the intrinsic "real" function when applied to a
-complex (or double complex) variable and passed as an argument to
-some intrinsic functions.  Example:
-	complex a
-	b = sqrt(real(a))
-	end
-  Fix glitch (only visible if you do not use f2c's malloc and the
-malloc you do use is defective in the sense that malloc(0) returns 0)
-in handling include files that end with another include (perhaps
-followed by comments).
-  Fix glitch with character*(*) arguments named "h" and "i" when
-the body of the subroutine invokes the intrinsic LEN function.
-  Arrange that after a previous "f2c -P foo.f" has produced foo.P,
-running "f2c foo.P foo.f" will produce valid C when foo.f contains
-	call sub('1234')
-	end
-	subroutine sub(msg)
-	end
-Specifically, the length argument in "call sub" is now suppressed.
-With or without foo.P, it is also now suppressed when the order of
-subprograms in file foo.f is reversed:
-	subroutine sub(msg)
-	end
-	call sub('1234')
-	end
-  Adjust copyright notices to reflect AT&T breakup.
-
-Wed Jul 10 09:25:49 EDT 1996
-  Fix bug (possible memory fault) in handling erroneously placed
-and inconsistent declarations.  Example that faulted:
-	character*1 w(8)
-	call foo(w)
-	end
-	subroutine foo(m)
-	data h /0.5/
-	integer m(2)	! should be before data
-	end
-  Fix bug (possible fault) in handling illegal "if" constructions.
-Example (that faulted):
-	subroutine foo(i,j)
-	if (i) then		! bug: i is integer, not logical
-	else if (j) then	! bug: j is integer, not logical
-	endif
-	end
-  Fix glitch with character*(*) argument named "ret_len" to a
-character*(*) function.
-
-Wed Jul 10 23:04:16 EDT 1996
-  Fix more glitches in the intrinsic "real" function when applied to a
-complex (or double complex) variable and passed as an argument to
-some intrinsic functions.  Example:
-	complex a, b
-	r = sqrt(real(conjg(a))) + sqrt(real(a*b))
-	end
-
-Thu Jul 11 17:27:16 EDT 1996
-  Fix a memory fault associated with complicated, illegal input.
-Example:
-	subroutine goo
-	character a
-	call foo(a)	! inconsistent with subsequent def and call
-	end
-	subroutine foo(a)
-	end
-	call foo(a)
-	end
-
-Wed Jul 17 19:18:28 EDT 1996
-  Fix yet another case of intrinsic "real" applied to a complex
-argument.  Example:
-	complex a(3)
-	x = sqrt(real(a(2)))	! gave error message about bad tag
-	end
-
-Mon Aug 26 11:28:57 EDT 1996
-  Tweak sysdep.c for non-Unix systems in which process ID's can be
-over 5 digits long.
-
-Tue Aug 27 08:31:32 EDT 1996
-  Adjust the ishft intrinsic to use unsigned right shifts.  (Previously,
-a negative constant second operand resulted in a possibly signed shift.)
-
-Thu Sep 12 14:04:07 EDT 1996
-  equiv.c: fix glitch with -DKR_headers.
-  libi77: fmtlib.c: fix bug in printing the most negative integer.
-
-Fri Sep 13 08:54:40 EDT 1996
-  Diagnose some illegal appearances of substring notation.
-
-Tue Sep 17 17:48:09 EDT 1996
-  Fix fault in handling some complex parameters.  Example:
-	subroutine foo(a)
-	double complex a, b
-	parameter(b = (0,1))
-	a = b	! f2c faulted here
-	end
-
-Thu Sep 26 07:47:10 EDT 1996
-  libi77:  fmt.h:  for formatted writes of negative integer*1 values,
-make ic signed on ANSI systems.  If formatted writes of integer*1
-values trouble you when using a K&R C compiler, switch to an ANSI
-compiler or use a compiler flag that makes characters signed.
-
-Tue Oct  1 14:41:36 EDT 1996
-  Give a better error message when dummy arguments appear in data
-statements.
-
-Thu Oct 17 13:37:22 EDT 1996
-  Fix bug in typechecking arguments to character and complex (or
-double complex) functions; the bug could cause length arguments
-for character arguments to be omitted on invocations appearing
-textually after the first invocation.  For example, in
-	subroutine foo
-	character c
-	complex zot
-	call goo(zot(c), zot(c))
-	end
-the length was omitted from the second invocation of zot, and
-there was an erroneous error message about inconsistent calling
-sequences.
-
-Wed Dec  4 13:59:14 EST 1996
-  Fix bug revealed by
-	subroutine test(cdum,rdum)
-	complex cdum
-	rdum=cos(real(cdum))	! "Unexpected tag 3 in opconv_fudge"
-	end
-  Fix glitch in parsing "DO 10 D0 = 1, 10".
-  Fix glitch in parsing
-	real*8 x
-	real*8 x	! erroneous "incompatible type" message
-	call foo(x)
-	end
-  lib[FI]77/makefile: add comment about omitting -x under Solaris.
-
-Mon Dec  9 23:15:02 EST 1996
-  Fix glitch in parameter adjustments for arrays whose lower
-bound depends on a scalar argument.  Example:
-	subroutine bug(p,z,m,n)
-	integer z(*),m,n
-	double precision p(z(m):z(m) + n)	! p_offset botched
-	call foo(p(0), p(n))
-	end
-  libi77: complain about non-positive rec= in direct read and write
-statements.
-  libf77: trivial adjustments; Version.c not changed.
-
-Wed Feb 12 00:18:03 EST 1997
-  output.c: fix (seldom problematic) glitch in out_call: put parens
-around the ... in a test of the form "if (q->tag == TADDR && ...)".
-  vax.c: fix bug revealed in the "psi_offset =" assignment in the
-following example:
-	subroutine foo(psi,m)
-	integer z(100),m
-	common /a/ z
-	double precision psi(z(m):z(m) + 10)
-	call foo(m+1, psi(0),psi(10))
-	end
-
-Mon Feb 24 23:44:54 EST 1997
-  For consistency with f2c's current treatment of adjacent character
-strings in FORMAT statements, recognize a Hollerith string following
-a string (and merge adjacent strings in FORMAT statements).
-
-Wed Feb 26 13:41:11 EST 1997
-  New libf2c.zip, a combination of the libf77 and libi77 bundles (and
-available only by ftp).
-  libf77: adjust functions with a complex output argument to permit
-aliasing it with input arguments.  (For now, at least, this is just
-for possible benefit of g77.)
-  libi77: tweak to ftell_.c for systems with strange definitions of
-SEEK_SET, etc.
-
-Tue Apr  8 20:57:08 EDT 1997
-  libf77: [cz]_div.c: tweaks invisible on most systems (that may
-improve things slightly with optimized compilation on systems that use
-gratuitous extra precision).
-  libi77: fmt.c: adjust to complain at missing numbers in formats
-(but still treat missing ".nnn" as ".0").
-
-Fri Apr 11 14:05:57 EDT 1997
-  libi77: err.c: attempt to make stderr line buffered rather than
-fully buffered.  (Buffering is needed for format items T and TR.)
-
-Thu Apr 17 22:42:43 EDT 1997
- libf77: add F77_aloc.o to makefile (and makefile.u in libf2c.zip).
-
-Fri Apr 25 19:32:09 EDT 1997
- libf77: add [de]time_.c (which may give trouble on some systems).
-
-Tue May 27 09:18:52 EDT 1997
- libi77: ftell_.c: fix typo that caused the third argument to be
-treated as 2 on some systems.
-
-Mon Jun  9 00:04:37 EDT 1997
- libi77 (and libf2c.zip): adjust include order in err.c lread.c wref.c
-rdfmt.c to include fmt.h (etc.) after system includes.  Version.c not
-changed.
-
-Mon Jun  9 14:29:13 EDT 1997
- src/gram.c updated; somehow it did not reflect the change of
-19961001 to gram.dcl.
-
-Mon Jul 21 16:04:54 EDT 1997
-  proc.c: fix glitch in logic for "nonpositive dimension" message.
-  libi77: inquire.c: always include string.h (for possible use with
--DNON_UNIX_STDIO); Version.c not changed.
-
-Thu Jul 24 17:11:23 EDT 1997
-  Tweak "Notice" to reflect the AT&T breakup -- we missed it when
-updating the copyright notices in the source files last summer.
-  Adjust src/makefile so malloc.o is not used by default, but can
-be specified with "make MALLOC=malloc.o".
-  Add comments to src/README about the "CRAY" T3E.
-
-Tue Aug  5 14:53:25 EDT 1997
-  Add definition of calloc to malloc.c; this makes f2c's malloc
-work on some systems where trouble hitherto arose because references
-to calloc brought in the system's malloc.  (On sensible systems,
-calloc is defined separately from malloc.  To avoid confusion on
-other systems, f2c/malloc.c now defines calloc.)
-  libi77: lread.c: adjust to accord with a change to the Fortran 8X
-draft (in 1990 or 1991) that rescinded permission to elide quote marks
-in namelist input of character data; to get the old behavior, compile
-with F8X_NML_ELIDE_QUOTES #defined.  wrtfmt.o: wrt_G: tweak to print
-the right number of 0's for zero under G format.
-
-Sat Aug 16 05:45:32 EDT 1997
-  libi77: iio.c: fix bug in internal writes to an array of character
-strings that sometimes caused one more array element than required by
-the format to be blank-filled.  Example: format(1x).
-
-Wed Sep 17 00:39:29 EDT 1997
-  libi77: fmt.[ch] rdfmt.c wrtfmt.c: tweak struct syl for machines
-with 64-bit pointers and 32-bit ints that did not 64-bit align
-struct syl (e.g., Linux on the DEC Alpha).  This change should be
-invisible on other machines.
-
-Sun Sep 21 22:05:19 EDT 1997
-  libf77: [de]time_.c (Unix systems only): change return type to double.
-
-Thu Dec  4 22:10:09 EST 1997
-  Fix bug with handling large blocks of comments (over 4k); parts of the
-second and subsequent blocks were likely to be lost (not copied into
-comments in the resulting C).  Allow comment lines to be longer before
-breaking them.
-
-Mon Jan 19 17:19:27 EST 1998
-  makefile: change the rule for making gram.c to one for making gram1.c;
-henceforth, asking netlib to "send all from f2c/src" will bring you a
-working gram.c.  Nowadays there are simply too many broken versions of
-yacc floating around.
-  libi77: backspace.c: for b->ufmt==0, change sizeof(int) to
-sizeof(uiolen).  On machines where this would make a difference, it is
-best for portability to compile libI77 with -DUIOLEN_int, which will
-render the change invisible.
-
-Tue Feb 24 08:35:33 EST 1998
-  makefile: remove gram.c from the "make clean" rule.
-
-Wed Feb 25 08:29:39 EST 1998
-  makefile: change CFLAGS assignment to -O; add "veryclean" rule.
-
-Wed Mar  4 13:13:21 EST 1998
-  libi77: open.c: fix glitch in comparing file names under
--DNON_UNIX_STDIO.
-
-Mon Mar  9 23:56:56 EST 1998
-  putpcc.c: omit an unnecessary temporary variable in computing
-(expr)**3.
-  libf77, libi77: minor tweaks to make some C++ compilers happy;
-Version.c not changed.
-
-Wed Mar 18 18:08:47 EST 1998
-  libf77: minor tweaks to [ed]time_.c; Version.c not changed.
-  libi77: endfile.c, open.c: acquire temporary files from tmpfile(),
-unless compiled with -DNON_ANSI_STDIO, which uses mktemp().
-New buffering scheme independent of NON_UNIX_STDIO for handling T
-format items.  Now -DNON_UNIX_STDIO is no longer be necessary for
-Linux, and libf2c no longer causes stderr to be buffered -- the former
-setbuf or setvbuf call for stderr was to make T format items work.
-open.c: use the Posix access() function to check existence or
-nonexistence of files, except under -DNON_POSIX_STDIO, where trial
-fopen calls are used.  In open.c, fix botch in changes of 19980304.
-  libf2c.zip: the PC makefiles are now set for NT/W95, with comments
-about changes for DOS.
-
-Fri Apr  3 17:22:12 EST 1998
-  Adjust fix of 19960913 to again permit substring notation on
-character variables in data statements.
-
-Sun Apr  5 19:26:50 EDT 1998
-  libi77: wsfe.c: make $ format item work: this was lost in the changes
-of 17 March 1998.
-
-Sat May 16 19:08:51 EDT 1998
-  Adjust output of ftnlen constants: rather than appending L,
-prepend (ftnlen).  This should make the resulting C more portable,
-e.g., to systems (such as DEC Alpha Unix systems) on which long
-may be longer than ftnlen.
-  Adjust -r so it also casts REAL expressions passed to intrinsic
-functions to REAL.
-
-Wed May 27 16:02:35 EDT 1998
-  libf2c.zip: tweak description of compiling libf2c for INTEGER*8
-to accord with makefile.u rather than libF77/makefile.
-
-Thu May 28 22:45:59 EDT 1998
-  libi77: backspace.c dfe.c due.c iio.c lread.c rsfe.c sue.c wsfe.c:
-set f__curunit sooner so various error messages will correctly
-identify the I/O unit involved.
-  libf2c.zip: above, plus tweaks to PC makefiles: for some purposes,
-it's still best to compile with -DMSDOS (even for use with NT).
-
-Thu Jun 18 01:22:52 EDT 1998
-  libi77: lread.c: modified so floating-point numbers (containing
-either a decimal point or an exponent field) are treated as errors
-when they appear as list input for integer data.  Compile lread.c with
--DALLOW_FLOAT_IN_INTEGER_LIST_INPUT to restore the old behavior.
-
-Mon Aug 31 10:38:54 EDT 1998
-  formatdata.c: if possible, and assuming doubles must be aligned on
-double boundaries, use existing holes in DATA for common blocks to
-force alignment of the block.  For example,
-	block data
-	common /abc/ a, b
-	double precision a
-	integer b(2)
-	data b(2)/1/
-	end
-used to generate
-	struct {
-	    integer fill_1[3];
-	    integer e_2;
-	    doublereal e_3;
-	    } abc_ = { {0}, 1, 0. };
-and now generates
-	struct {
-	    doublereal fill_1[1];
-	    integer fill_2[1];
-	    integer e_3;
-	    } abc_ = { {0}, {0}, 1 };
-In the old generated C, e_3 was added to force alignment; in the new C,
-fill_1 does this job.
-
-Mon Sep  7 19:48:51 EDT 1998
-  libi77: move e_wdfe from sfe.c to dfe.c, where it was originally.
-Why did it ever move to sfe.c?
-
-Tue Sep  8 10:22:50 EDT 1998
-  Treat dreal as a synonym for dble unless -cd is specified on the
-command line.
-
-Sun Sep 13 22:23:41 EDT 1998
-  format.c: fix bug in writing prototypes under f2c -A ... *.P:
-under some circumstances involving external functions with no known
-type, a null pointer was passed to printf.
-
-Tue Oct 20 23:25:54 EDT 1998
-  Comments added to libf2c/README and libF77/README, pointing out
-the need to modify signal1.h on some systems.
-
-Thu Nov 12 15:34:09 EST 1998
-  libf77, libf2c.zip: minor tweaks to [de]time_.c and the makefiles,
-so makefile.sy, makefile.vc, and makefile.wat deal with [de]time_.c.
-
-Wed Feb 10 22:59:52 EST 1999
-  defs.h lex.c: permit long names (up to at least roughly
-MAX_SHARPLINE_LEN = 1000 characters long) in #line lines (which only
-matters under -g).
-  fc: add -U option; recognize .so files.
-
-Sat Feb 13 10:18:27 EST 1999
-  libf2c: endfile.c, lread.c, signal1.h0: minor tweaks to make some
-(C++) compilers happier; f77_aloc.c: make exit_() visible to C++
-compilers.  Version strings not changed.
-
-Thu Mar 11 23:14:02 EST 1999
-  Modify f2c (exec.c, expr.c) to diagnose incorrect mixing of types
-when (f2c extended) intrinsic functions are involved, as in
-(not(17) .and. 4).  Catching this in the first executable statement
-is a bit tricky, as some checking must be postponed until all statement
-function declarations have been parsed.  Thus there is a chance of
-today's changes introducing bugs under (let us hope) unusual conditions.
-
-Sun Mar 28 13:17:44 EST 1999
-  lex.c: tweak to get the file name right in error messages caused
-by statements just after a # nnn "filename" line emitted by the C
-preprocessor.  (The trouble is that the line following the # nnn line
-must be read to see if it is a continuation of the stuff that preceded
-the # nnn line.)  When # nnn "filename" lines appear among the lines
-for a Fortran statement, the filename reported in an error message for
-the statement should now be the file that was current when the first
-line of the statement was read.
-
-Sun May  2 22:38:25 EDT 1999
-  libf77, libi77, libf2c.zip: make getenv_() more portable (call
-getenv() rather than knowing about char **environ); adjust some
-complex intrinsics to work with overlapping arguments (caused by
-inappropriate use of equivalence); open.c: get "external" versus
-"internal" right in the error message if a file cannot be opened;
-err.c: cast a pointer difference to (int) for %d; rdfmt.c: omit
-fixed-length buffer that could be overwritten by formats Inn or Lnn
-with nn > 83.
-
-Mon May  3 13:14:07 EDT 1999
-  "Invisible" changes to omit a few compiler warnings in f2c and
-libf2c; two new casts in libf2c/open.c that matter with 64-bit longs,
-and one more tweak (libf2c/c_log.c) for pathological equivalences.
-  Minor update to "fc" script: new -L flag and comment correction.
-
-Tue May  4 10:06:26 EDT 1999
-   libf77, libf2c.zip: forgot to copy yesterday's latest updates to
-netlib.
-
-Current timestamps of files in "all from f2c/src", sorted by time,
-appear below (mm/dd/year hh:mm:ss).  To bring your source up to date,
-obtain source files with a timestamp later than the time shown in your
-version.c.  Note that the time shown in the current version.c is the
-timestamp of the source module that immediately follows version.c below:
