Emacs-22.1 compilation-error-regexp

[Bob McIsaac]

The compilation-error-regexp works for gcc output but not for
Openwatcom. However, it worked fine for emacs-21. It seems the regexp
no longer accepts parentheses around the line number.

----- gcc example is ok ----
-*- mode: compilation; default-directory: "c:/altm/acp-7-3/build/" -*-
../src/vi/vi_main.c:53: `xint' undeclared (first use in this function)
../src/vi/vi_main.c:53: (Each undeclared identifier is reported only once

------- Open Watcom Make Version 1.7 -- not ok because of line number ======
