If you decide to work it out please let me know. There is no equivalent for any non-gcc unix compiler I am aware of. I think all of the Win32 compilers have some form of macroized inline assembly, but that doesn't do much good here. If you want to support these other compilers you'll have to use straight assembly. r~
