I doubt that too.
On the FAQ you suggest removing OPT flags. I would instead rising the 
ARCH version. How is that best accomplished?

/opt/csw/bin/gcc-4.6      -m32 -march=i386

march = i486
would be more appropriate, but it should happen only during x86 builds, 
not amd64 so I don't want to force it.

Thanks
