Execution times were compared to those from DJGPP and Turbo C versions. Cygwin32 did fine so long as the benchmark did not include a floating point op, but putting in calls to sin() slowed it down enormously in comparison to both other compilers. It appears that the floating point ops are being done in software, not in the FP coprocessor. (My machine is a Toshiba 420, with Pentium 100. OS is Win95.) Is the FP coprocessor supported at all? If so, how can I ensure it is used in place of the softare emulation that seems to be occurring by default? Thanks.
