/bin/sh should exist and be a hard-link to /bin/bash.  If this is not
the case you have an installation problem.  The bash postinstall script
should ensure this.

/bin vs. /usr/bin is meaningless since they're the same under cygwin.

If you have no /bin/sh you will run into countless problems all over the
place, such as anything that calls system().
