gcc/Makefile.in contains the po/gcc.pot target, which uses po/exgettext.

I assume that somewhere there is some list of functions that take translatable
strings, since xgettext has to decide which of these functions take
printf-style arguments and which take gcc-internal-style arguments.

The gfc_internal_error function should be removed from that list. I could not
find this list anywhere, though.
