Ah yes.. good point.

I'll probably wind up using Wine's makedep for my project then.  If I 
recall though, it had issues with includes that were only included if 
something was specifically defined.  Maybe I should take another look at 
it.  X11's makedepend still chokes on #if's with logical operators and 
also likes to generate dependencies for the system headers too which just 
fills up the makefile with tons of dependency info.

Maybe I can find some time to look through and extend Wine's makedep to be 
a bit more usefull for projects other than Wine.  Or maybe I should read a 
bit more documentation on it first. :-)
