Exactly. Since ggcc 4.0 [1], the output of GCC is uTF-8, if the locale
allows. So your best bet is to do what Pascal suggests or even more
radically call "LC_ALL = C gcc" instead of just "gcc" to turn off this
"feature". You might tweak the environment your compile subprocess sees
with setenv in Emacs.

[1] See <http://gcc.gnu.org/gcc-4.0/changes.html> under "Caveats", and
search for the phrase "English-language diagnostic messages".
