I was using Make 4.1, you can find it here:

  http://www.delorie.com/pub/djgpp/deleted/v2gnu/mak41br2.zip

And if we are talking versions, then you may bump into problems with
latest GCC versions.  If so, try the versions I used:

  GCC 3.4.6
  Binutils 2.26
  GDB 7.2

It's hard to know if it's a known problem, but I never used that
version of Make in its DJGPP port.  Is the crash reproducible?  If so,
what recipe in lib/Makefile crashes it?
