It would even be possible to add a --disable-dependencies option that
turned this off if you want to support developers on really slow
machines.

There are two different dependencies here:

 - When a .c file is changed, proto.h should be rebuilt.  Users who
   want to download and build Samba without modifying the source won't
   need awk because the header will never be rebuilt.  The mtime of
   proto.h should not change unless there were actual differences in
   the headers.

 - When a .h file is changed, all .c files that depend upon it should
   be rebuilt.  (For Samba at the moment this means everything.)

I would argue that it is better to have the build process be slower
sometimes than to have the tree break because somebody forgot to do
"make clean" in their pre-checkin build.  "uncompiled code is broken
code, etc".
