I'm cross-compiling for a Power PC running BSD/OS 2.0.1 from an
i386 running BSD/OS 2.0.1...  If -mpower is not enabled, gcc 2.7.2
dumps core when trying to generate code for a post-increment of a
long long variable:

------------------------------------------------------------------------
% cat pos.1.c
void bar(long long);

void
foo(long long i)
{

        bar(i++);
}
% cc -v -O2 -S pos.1.c
