| "Something similar".  Basically, it provokes the compiler into producing

I added this type of functionality to GCC's cpp.  I added a new switch
-MD, which runs the compile as normal, but places the dependency list
for foo.c into foo.d in the current directory (CMU had done a similar
thing previously).  Part of the OSF/1 build process uses this and
automatically updates the Makefiles.  It was fairly simple to do
providing you have source to the compiler (or a tame compiler wizard
on hand)....

Considering the flames and intolerance, shouldn't USENET be spelled ABUSENET?
