Also if an user supplies -mno-sse or even -mno-mmx, -mno-sse3 is
supplied by default which means they will not get fisttp at all which is
not what the user wanted.  He used want to disable the vector
instructions and nothing more.

I disagree, -mno-sse3 should turn off all sse3 instructions and now you and I can stop this discussion and await an i386 maintainer.
