Emacs and GFortran

[Alfred M. Szmidt]

Steve, you are being silly.  The change is not invasive, hard, or
causes a burden for gfortran developers.  The `GNU error style
message' works perfectly well with multi-line messages, as was shown
with g77.

+  error_printf ("%s:%d:\n", f->filename,
 #ifdef USE_MAPPED_LOCATION
          LOCATION_LINE (lb->location)
 #else

The above will make things parsable by things that parse GNU style
error messages.  You could even make it backward compatible with the
current format which gcc/testsuite/lib/gfortran-dg.exp expects by
simply adding "FILE:LINENO:" above the "In file" message, much like
g77 did!

Sighs...
