I have the solution to your problem, but I don't have the file here at
home, it is at work. If I remember right the Makefile looks something like

OS = $(shell uname)

ifeq ($OS,Linux)
ifeq ($OS,MINGW)
CMD_NAME = cmd.bat

In mingw (msys) as well as cygwin you have access to the uname command. As
you are using gnu make I guess that you are in one of those environments
on Windows? If you don't have access to the uname command on Windows,
maybe it would be possible to call ver instead.

If I remember right I had to strip of some text from the $OS-variable in
Windows, I think that both Cygwin and MINGW adds a lot of version
information in the output from uname.
