I know this program will run on a Windows 2000 Intel pentium 4 machine. The program is time critical, and I really want to make it run as fast as possible. Which parameters and options should I send to gcc when compiling and linking? I'm using mingw 2.0 with gcc 3.2. gcc --version gcc (GCC) 3.2 (mingw special 20020817-1) I'm willing to update the compiler if that will increase the execution performance of the binary. -=D8ystein [*] It's a neural net based backgammon evaluation program based on GNU Backgammon ------------------------------------------------------------------- The information contained in this message may be CONFIDENTIAL and is intended for the addressee only.
