No, that it generates bad code for RISC platforms.  While the core
(on the other side of the microcode) of many x86 processors is RISC,
IA32 is not RISC.

It isn't a good compiler.  It sucks on the majority of the platforms it
runs on.  If it runs stellar on one platform, that's hardly indicative
of a good product.

All compilers have extensions, yes.  However, vendor's compiler have
switches for flagging those extensions.  RMS himself once said (I think
it's in the GCC info page) that the ANSI-enforcing arguments to GCC are
basically a joke because it's not a priority of theirs and they
implemented it just to have something to wave at pedants (of which I am
one, I guess).

Which Intel CPUs support 3DNow!?
