Description:
it would appear from quick comparison, that the fpc compiler is not
using the floating point registers. Almost identical code compiled
with gcc is almost 2x faster and the only real difference I note in
the tight loops is the lack of fp unit stack use.
FYI.
Steps to reproduce:
mandlebrot benchmark is easiest
