It *sounds* useful, but we did without that feature so far.  Hmm.  It 
would make it easier to use headers -- any dependency to other files are 
already taken care of.  Since we have less .h files than .c files this 
seems to make sense.

Would it perhaps also make using precompiled headers easier (or possible 
in the first place)?  Do we care?
