Here is the message in my compile window as it is displayed by -next:

ARGV:148: ERROR: need a space before the open parenthesis '('
#148: FILE: home/mdday/src/slp-devel/src/cmd-utils/lslp-linux.c:145:
+  if(dieNow)

The filename is reported as ARGV and the line number is reported as
148. These should be FILE: #line:FILE: \basename\filename:line: 

Also, the line number is reported differently. The correct line number
is reported at the end of the second line.

I tested these patches with both sources and patches, from bash and from emacs and they seem to work ok.
