xfree86 compilation / gcc-3.3 strict aliasing

[Matthias Klose]

Looking at the build logs you'll see many warnings:

    dereferencing type-punned pointer will break strict-aliasing rules

Is it safe to ignore these warnings? Please could you try to compile
using -O2 -fno-strict-aliasing to see if this is related to the recent
miscompilation using gcc-3.3?

Thanks, Matthias
