bug#6778: 24.0.50; compile-mode fails on gcc-4.5 error messages |

Emacs compile.el fails to parse correctly gcc 4.5 error messages that
include a column as well as a line number.
To reproduce, assuming gcc 4.5 is installed as "gcc-4.5":
(1) Put the following text into a file "x.c":
int y = 1;
int z = q1;
int p = 1;
(2) Now compile by doing "M-x compile", and for a compilation command,
use "gcc-4.5 -c x.c".
(3) The compiler will output an error message like:
-*- mode: compilation; default-directory: "/tmp/" -*-
Compilation started at Mon Aug 2 23:07:40
gcc-4.5 -c x.c
x.c:2:12: error: ‘q1’ undeclared here (not in a function)
Compilation exited abnormally with code 1 at Mon Aug 2 23:07:40
(4) One should be able to jump to the error by giving the command
`next-error' ("C-x `"); however next-error apparently is confused
by the error, and instead gives a prompt like:
Find this error in (default x.c:2): /tmp/
Apparently it fails to recognize the FILE:LINE:COL: format, and thinks
that ":2" is part of the filename.
My recollection is that such error messages used to be properly parsed
by next-error, so maybe some recent change has broken this.
Thanks,
-Miles
