Chess Tiger compiled with GCC is practically as fast as when compiled with MSVC
5.0.
In fact I use GCC all the time and the version that will compete in the World
Championship will be compiled with GCC.
GCC and all the integrated environment fits on 3 floppy disks, which is very
convenient when you have to travel. The only drawback is that GCC compiles
slower than MSVC (but with todays computer, who cares). The EXE speed is almost
the same.
Another advantage is that GCC produces DOS executables. When you want to have
accurate speed measures, you have to run your program in pure DOS (Windows
steals time randomly), and that's something you cannot do with a MSVC
executable.
