OK, mine was Msys/mingw on XP.

I'm still using the stable mingw - 3.4.2 or something, I think?
Anyway, no gettimeofday...

I didn't get a chance to really look, but adding a glGetString() call
for GL_EXTENSIONS didn't seem to show either GL_TEXTURE_RECTANGLE_ARB
or GL_TEXTURE_RECTANGLE_EXT support on my test machine. I had
imagined that GL_TEXTURE_RECTANGLE_EXT might show up... The png's, of
course, aren't 2^n sizes... Everything just comes up as white on a
white background...
Also, no text is appearing either, for reasons I haven't had a chance
to look into.

I'll give that a shot tomorrow, if I get a chance.
