Add $Id$, to make it simpler for members of the translation teams to

track. The $Id$ line is normally at the bottom of the main comment block in the man page, separated from the rest of the manpage by an empty comment, like so; .\" $Id$ .\" If the immediately preceding comment is a @(#) format ID marker than the the $Id$ will line up underneath it with no intervening blank lines. Otherwise, an additional blank line is inserted. Approved by: bde

Update to the most recent version. Among other things, this also solves

1999-02-03T17:23:49Z

the function naming problem for complex double function i've recently aksed for in -committers. (The recently committed rev 1.5 of proc.c was actually also part of this update.) Should the mailing lists come to an agreement that f2c better belongs into the ports, this could be done nevertheless. For the time being, we've at least got a current version now. Thanks, Steve!

Replace 'long int' with 'int' for Alpha.

This change should have no effect on i386. Pointed out by: Steve Kargl Quote from http://www.netlib.org/f2c/readme: 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.

I found the reason why f77 so offen dies on alpha. Here is a fix. "Const" is a union of int and double. If nelt->constblock.Const.ci > 0 then it trys to evaluate it as double and floating point exception occurs. Submitted by: Hidetoshi Shimokawa Obtained from: NetBSD

During compilation of a Fortran program f2c/f77 will spew the

1998-07-24T07:13:57Z

name of entry points, functions, subroutines, and program to stderr error. The enclosed patches do 3 things: (1) Silenced the output to stderr. (2) Added a -v option to f2c and f77. This will turn on a verbose mode, and dumps quite a bit of stuff to stderr. (3) Updated the f2c man page. PR: 7369 Submitted by: Steven G. Kargl

Fixed `make -jN' for large N. Just put all generated headers in SRCS.

Use the same format for the "expect N shift reduce conflicts" message

as in the one other place in /usr/src that prints such an "expect" message (amd).
