Yes, I think you're right. Perhaps the SSE2 support should be turned into an --enable-sse2 configure option, that's disabled by default? One problem with this is that I don't know how to enable SSE2 instructions for compilers other than gcc, so the option would only apply to gcc-based systems. Disabling SSE2 would just mean that all x86/gcc systems would end up using the inline assembler to get and set the control word; so we'd still get short float repr everywhere we did before.
