Folks, In the "vs2008" branch of the Gambit fork at http://github.com/goetter/gambit I have an nmake-compatible set of Makefiles that build Gambit with Microsoft Visual Studio 2008, that is, without the tools of mingw or msys. It supports make bootstrap and make bootclean, but not yet make update (I have a suitable script that I'll test once the master branch advances a couple more releases). To use, from the topmost Gambit source directory, type misc\winbuild. You may need to edit this batch file if your copy of VS2008 is installed to a drive other than C: winbuild currents knows the following targets: clean, bootclean, realclean, bootstrap, all. This environment will build a native Win64 Gambit as well. You will need to edit misc\winbuild.bat and misc\winconf.mak per the comments in each. I will fix bugs in this branch as I find them (win64 + wide character system calls is good for flushing out such), and will offer those fixes to Marc for possible incorporation into "master" as appropriate. (If I've erred, please let me know. My git-fu is weak.) Ben
