Here's the full story. I'm trying to build apr. It needs to be built
with mingw in order to have thread support. It specifically disables
thread support with cygwin. So, instead of getting the mingw
environment, I'd like to use the cygwin environment cause I my build
system builds many other packages.

I can't figure out how to get past this problem. Any help at all would
be greatly appreciated. 

I even tried putting ~/bin/cat in my path, where cat does dos2unix and
then calls /usr/bin/cat, but that didn't work either. I'm not sure why.

I was sort of looking for a solution that was "clean".

Thanks,
