cppfiles.c:955: Internal compiler error

Thanks for your bug report. As you may know, this is caused by using
--enable-checking. So if you just want to built the compiler, omit
this option. If you do know this is the cause of the problem, it would
be even better if you tried to analyse the problem further; starting
with a debugger, and perhaps even submitting a patch...

Regards,
Martin
