This is odd.

Each process has its own copy of "PATH", and Emacs provides facilities
for changing it. So perhaps your .emacs is changing PATH to not
include Cygwin; look for "setq exec-path". Although in that case you
should not be able to start bash in the first place.

I've also had trouble with the Cygwin prompt, which wants to do color
and stuff. Try creating a file '.emacs_bash' in $HOME, containing:

export PS1="address@hidden "

That will give you a simpler prompt.

I also use a customized Emacs routine to launch a shell; if the above
doesn't fix your problem, see 'shell-mode-keys.el' in
stephe-emacs.tar.gz at http://www.toadmail.com/~ada_wizard/

I also have complete instructions for installing my current work
development environment on Windows, at
http://fsw.gsfc.nasa.gov/gds/tools_install_windows.pdf. That may
provide some helpful clues.

Good luck. The struggle is worth it :).
