I never used makedepend, but what are the issues?
I was thinking more like a gcc -MM thing, but more portable, and
possibly with dependency caching. It should really decrease built
times for incremental compiling I guess. Which seems usually big
nowadays.

AM> A couple of the issues with makedepend are:

1) gathering all the -D and -I options that must be
   shared between the compiler and makedepend.
2) it is a separate tool that takes time to run -- so 
   running it becomes optional, hence it doesn't get done.
