GNU has a "Bison for Windows" page where the source and binaries are offered.
But I am guessing that the Windows binaries were built using the GNU C/C++/G/G++ (?) compiler with a WINNT/WIN32 switch, rather than setting up the source with a VC++ project. I see the nothing but input files like configure and Makefile to be set up using bash.
[Stop me if I made a mistake up to this point.]
Suppose I want to set up the source and headers as VC++ project. Aside from trying to read 3000 lines of shell script to figure out how to make "config.h", what is the best way to go about it?
