  Although I installed f2c on BSD/OS 2.0, they do not work as I
expected. My machine is Gateway2000 P5-90, so I expected the
performance is about three times faster than Sun IPX as the
byte-benchmark3.1 shows. However, it approximately same as the
latter. Why? It seems not to use FPU. The major part of my fortran
codes is floating-point calculation. My linker options are simply
"-lf2c -lm".

Help me, please. 

Thanks,
  Hiro
