This binary can be used on Windows 95/98/2000/XP/NT/ME.
The binary was built using the MinGW collection of header files and import libraries. These allow one to use GCC and produce native Windows32 programs that do not rely on any 3rd-party DLLs.
minGW is included in the the cygwin unix environment for windows. The build was done from cygwin with gcc -mno-cygwin
Gnu Go does not come with its own GUI. The win32 binaries work very well with the Jago go server client. See the Gnu Go homepage for links to Jago.
