This is fairly unrelated to the actual posting in this thread that I replied
to. This is the only one still in my mailspool, so I keep it.
The AWK version of "make dep" took, on average, a little over an hour here.
Sometimes it would take as long as four or five for reasons I never found.
Linus' mkdep.c did it in about 10 minutes.
The machine? 386/20 with a Cyrix 386->486 (aka "Warmed over 386") chip with
1K cache, and 8MB RAM. No active swapping from GCC.
