Comment (by waddlesplash):

32 bit gcc2hybrid, real hardware.

 GCC 2 is a very old compiler that does not have good optimizations.
 Windows is of course compiled with a much newer compiler that can optimize
 significantly more, so even before actual code behavior is taken into
 account, this is a significant difference. Can you please retest on 64-bit
 Haiku?
