In addition to adding `static' where possible: - bin/date: Move `retval' into extern.h to make it visible to date.c. - bin/ed: Move globally used variables into ed.h. - sbin/camcontrol: Move `verbose' into camcontrol.h and fix shadow warnings. - usr.bin/calendar: Remove unneeded variables. - usr.bin/chat: Make `line' local instead of global. - usr.bin/elfdump: Comment out unneeded function. - usr.bin/rlogin: Use _Noreturn instead of __dead2. - usr.bin/tset: Pull `Ospeed' into extern.h. - usr.sbin/mfiutil: Put global variables in mfiutil.h. - usr.sbin/pkg: Remove unused `os_corres'. - usr.sbin/quotaon, usr.sbin/repquota: Remove unused `qfname'.

Make this code WARNS=6 clean again (after GCC 3.1.1 import).

o __P has been reoved

o Old-style K&R declarations have been converted to new C89 style o register has been removed o prototype for main() has been removed (gcc3 makes it an error) o int main(int argc, char *argv[]) is the preferred main definition. o Attempt to not break style(9) conformance for declarations more than they already are. o gc some #ifdef sun ... #endif code Approved by: arch@, new style(9)

o Correctly define rcsid.

o Add consts where appropriate. o Rename some variables that were shadowing global declarations. o Remove register storage-classes. o Make errmsg a const, so we can just set error messages instead of using sprintf/strcpy. o Set WARNS=2 Reviewed by: bde, des

Use PATH_MAX rather than MAXPATHLEN. Also fix a possible off by one

error caused by the -1 being on the wrong side of the comparison. This would not cause an overflow, as near as I can tell, because we truncate later anyway. We'd just fail to get a diagnostic for 1024 and 1025 byte file names.

sccsid -> rcsid and fix some minor nits.
