You should be able to run the same binaries from the bash shell,
provided that you make sure there is a unique cygwin DLL in your path.
 I bundled the cygwin
DLL with the win32 versions of GrADS so that installing cygwin did not
become a requirement. Here is what suggest you do:

1) start cygwin with the bash shell and cd to directory where the
grads binaries are installed and start one of the executables:

$ cd c:/Programs Files/PCGrads/xwin32         (check dir name)
$ ./gradsnc

If it complains that there 2 cygwin DLLs in your path, then rename the
one bundled with grads and use the one in your cygwin installation.
Make sure it starts.

2) Now, the gradshdf.exe is actually a wrapper that sets all kinds of
environment variables before actually starting the executable under a
native rxvt - there is bit of black magic in these wrappers meant to
approximate the "windows experience", in addition to providing a
better terminal than cmd.exe. The good thing is, you don't need it.
You will find files like gradshdf.dll, gradsnc.dll -- these are not
DLLs, but simply the real command line executables. So, if you

$ mv gradsnc.exe gradsnc-wrapper.exe
$ mv gradsnc.dll gradsnc.exe

you will now have a gradsnc just like on Linux/Unix: you will have to
set the GADDIR, GASCRPT as usual.

If all fails, rebuild or wait for my build for v1.9.0 sometime in the Fall.

  Good Luck,

       Arlindo
