Emacs has a nice feature for allowing one to compile C programs (make) and
jump to syntax errors with ^X^N. Unfortunately, the F77 error output format
is not the same as C and so emacs doesn't understand it. The following mods
to the f77 compiler (f77pass1) will output errors diagnositics in the correct
format. This approach was taken rather than writing a post f77 error filter
because it is MUCH faster within emacs (no forking subshells, etc.)

Unfortunately, it breaks the handling of errors for '/usr/ucb/error'.
Sorry. We don't use /usr/ucb/error around here much.
Most of our users are emacs-f77 users, so the change is helpful.

This was done on bsd4.2. All other flavors are on their own.

Use 'patch' to make the changes to /usr/src/usr.bin/f77/src/f77pass1/error.c

This diff was made with:  diff error.orig.c error.c
