It's been a long while since I looked (probably back in DOS days with 
Borland compilers), but I seem to recall that "long double" is the magic 
incantation required to use 80-bit floating point.

Please send the patch my direction; there's no real reason not to have it, 
other than lack of time on my part.  Although I think I agree with you 
that it should probably be disabled by default so people could build 
straight from a snapshot without needing to have any tools other than VC8 
installed.

That's a good idea; I've disabled the warnings in the yasm build portion 
by defining that macro in the vc8/config.h file, but you still get the
warnings for the tools (like re2c) that don't include config.h.  Doing it 
in vsprops sounds like a better idea; please send me the patch and I'll 
get it incorporated.

Thanks,
