It seems similar to what Digital Mars, Borland C, and OpenWatcom support. However, neither DJGPP v1's compile nor any subsequent GCCs seem to have incorporated this feature. Granted, it's unofficial, maybe they didn't think it worked well enough, or maybe full FPU emulation was considered more accurate or better somehow. Just curious if anybody has any thoughts. (I don't have a buggy Pentium to test either.) gcc-2.6.3-fdivpatch.bz2 24-Dec-1994 00:00 28K gcc-2.6.3.tar.bz2 01-Dec-1994 00:00 4.6M http://gcc.cybermirror.org/old-releases/gcc-2/
