why is make so bloody slow (for me)

A little more info.  I executed the code in the $(shell ...) in a
bash, and it, too, was pretty slow.  Just a few grep's and sed's.
Seems like the subprocess creation and waiting-for-termination is just
generally slower (on windows 2000, I'm guessing).

  I'm running Windows 2000 on a PIII 700 with 256mb of PC100 ECC RAM.
  It's not the machine, obviously.  It's probably win2k, but I thought
  I'd ask...

  I'm running the V1.0 of cygwin.

  The command "make --debug" gives this output:

  There is a 10 second pause after each of the above 4 lines is
  printed.  The overall effect is that it takes a good minute or two to
  get to doing some real work.

  I upgraded my processor and NT (from 4.0sp6a) around the same time,
  but I can swear it never was this slow.

  I have a bunch of $(shell ...) in lines my makefile.
  I have the environment variable MAKE_MODE set to UNIX.
