Explicitly mention fil41b.zip as a required djgpp component.
Oddly, some people only pick up part of djgpp, then
complain to us when the Makefile doesn't run as
planned.
<Someone> reports that someone on the
newsgroup tried to use the MSVC 1.52c (16 bit compiler) Makefile
with MSVC 6 (32 bit compiler). Try to make it more obvious
that the Makefile isn't for that.
