Knock wood. The win32 build went relatively painlessly, and I am delighted to see ProjectBuilder files for FGLT as well as VC++ dsws.

The only problem is that I still need to toss together a C wrapper since CL cannot talk to C++, and FGLT is C++, with classes and everything. :)

But guess what? I have decided one step at a time, and I am hoping/praying that the easier step is to get X under my belt by settling for built-in GLUT fonts for now.

I'll take a swing at running Cello against Mac OS X Glut just to get some encouragement, then look at building Freeglut on Mac OS X in Unix-mode to get X on Cello's resume (Apple's Glut uses native windows).
