There's no dependency between sed.c and the file that changed (the header file 
with all the #defines for config info.)

Of course if there WAS, every config change in unrelated parts of the code 
would cause suprious rebuilds of every fil that cared about a config change.

In theory, makedep should be able to do something about this.  I wonder how 
the linux kernel people solved it?
