I have seen this before.  What happens is that GNU make sets MAKEFLAGS
to "--unix"
automatically (or some similar version of that variable).  nmake also
reacts to the
MAKEFLAGS variable and it complains because it does not know the
"--unix" option.

The workaround I used was to create a batch file.  In the batch file,
explicitly clear
MAKEFLAGS and then call nmake.  Replace your call to nmake with a call
to the batch
file.

Good luck.
