next-error fails to parse gcc output

[Gregory Stark]

M-x next-error is being confused by output from gcc of the form:

In file included from guc.c:6433:

which it considers an error line and prompts me to tell it where to open the
file named "In file included from guc.c" In previous versions of emacs it
ignored this line entirely.
