I have been trying to do autoconf builds on OSX ... I have reasonable 
success doing this for other projects (Worldforge, etc), to the point 
where I feel I understand autoconf/make pretty well ... but I still 
can't get configure to run right. (Running autoXXX all work fine) ... 
basically config.guess is being created empty. I *think* my Fink 
install may be screwed up (0.4.0 migrated to CVS for Jaguar support) so 
once Fink 0.5 is out I'll rm -rf /sw and try again :-)

In that vein, there is a common configure.ac structure we should be 
taking advantage of that would simplify the platform aspects of the 
script significantly, and also move many of the platform specific 
header / lib checks out of the general path. it looks like this:

AC_CANONICAL_HOST
case $host in
*-apple-darwin*)
	....
	AC_CHECK_HEADER(/System/Library/OpenGL/iinclude/gl.h)
	...
	;;

*-*-cygwin-* | *-*-mingw32*)
	.... win32 specific stuff
	;;

*-*-irix-*)
	.. irix specific stuff
	;;
esac

Obviously some things are better handled with specific tests but this 
does nicely isolate lots of platform specific checks / code.  I was 
going to have a go at adding such a thing to configure.ac, but wanted 
to wait until I'd built successfully with an un-modified version before 
going further.
