Subject: Crafty 16.8 on NT4.0 using VC++ 6.0 SP3: Speed improvement....

It appears that Microsoft fixed some serious optimization bugs in VC++ 6.0.
Using Makefile.nt and SP3 for VC++ 6.0, use /Ox /G6 /Gr instead of /O2 /G6 /Gr
/Ob2 when building your code. The difference is 198,147 to 189,966 on some old
dual p6/200. I am using individual object code generation (each .C file has its
own .OBJ file) and no /DFAST. This might additionally speed up things.
