You want #include <ieeefp.h> -- that works on i386 & alpha. BTW, FP_X_DNML isn't defined on alpha. I posted some patches to freebsd-alpha on Tue Nov 27 11:07:15 to get Mozilla to build, but I never got it working -- it kept dying in Javascript. Perhaps your thread fixes will cure this. You might want to pull my patches out of the mailing list archives.
