[x264-devel] configure contains incompatible flags, build fails with Sun Studio

Hi again,
building x264 witn Sun Studio 12U1 on opensolaris, it fails saying

I had to remove the setting of
-ffast-math and -fomit-frame-pointer flags from the configure file
to make it proceed. I guess this is something gcc just ignores, but
Sun Studio does not.
