If you issue a make depend command in a project, the file  
Makefile.dependencies contains references of *ALL* the appkit headers for  
each object file. This produces HUGES dependencies list (more than 100Kb),  
slowing down the make process.

To build the dependencies make depends issues 'cc -MM <all sources> |  
awk...' and the cc manual says

     -MM  Like -M but the output mentions only the user-header
          files included with #include "file".  System header
          files included with #include <file> are omitted.

So why are all imported <appkit/xxx.h> listed ? Is that because of #import  
instead of #include ? I don't care having dependencies with them.

I currently use a sed script to remove all this stuff. My makes are now  
going somewhat faster. The first command issued appears after one second  
instead of something like 5 or more seconds.
