okay, whenever you see "process_begin: CreateProcess((null)..."
from gmake in windows, it means it couldn't find the command line
compiler. so, the fbuild directory uses gcc only and you probably
don't have it installed.

these are cycle timing numbers. the "OptimizeXXX" perl scripts run
the "test_xxx" programs many times to find the optimum code generation
parameters.

the fbuild system is a prime candidate for tidying up and making cross
platform. the current ODE build uses code optimized for a pentium III
only. on other platforms (MIPS for instance) you can do better.
