Could these be accumulated rounding errors? the x86 architecture does not
support ieee fp (unless done in software ;->), so optimizations can cause
different results, even if the code looks the same.

You can try to work around this by linking against -mieee and using
-ffloat-store.

Just call it, if compiled correctly (I assume so) it will find istelf:

/usr/local/bin/pgcc (It might be named differently, like
/usr/local/pgcc/bin/gcc)

Maybe Mandrake has newer versions as a mandrake-rpm-package?
