Make will try to find a /bin/sh, and use it if found in your PATH.

I didn't even know I had a make on my site. Just for kicks, could you try
out any mingw make, from say Jan-Jaaps (URL below) site, and see if it
still causes the problem? Also, you may want to remove /bin from your
PATH and see if that does anything.

fyi, I'm now more in favor of using Cygwin tools to build both Cygwin
and Mingw binaries/executables (using -mno-cygwin) to avoid these 
hassles. With b20.1 being quite stable on NT, and reasonably stable
on W9x using the 1999-01-16 snapshot on Cygnus site, it's looking
better and better.

My personal preference is to use a Linux box and cross-compile ...

Mumit
