No, gcc 4.4.0 works on multiple platforms. The issue the Arch people
are seeing happens to cause problem on at least gcc 4.2.x - see
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=28671#c8 - and the correct
thing to do is to not compile gcc with arch or march settings. I have
fixed 95% of #2999-3001 in all spkgs which would all to inject flags
like march into each spkg.

It is the default compiler on skynet and the reason GAP miscompiles on
Itanium. OH well....
