This is one of the common pitfalls people encounter with Cygwin: /bin/sh
is *not* bash, it's ash.  Therefore, scripts written with the assumption
that /bin/sh is bash (as it is on some [most?] Linux distributions) fail
on Cygwin when they encounter bash-isms.  They would also fail on any
other Unix where /bin/sh is not bash.  This is a portability problem in
the scripts, and should be fixed there (if only by changing the shebang to
#!/bin/bash).

The usual (and preferred) way of providing details about your installation
in problem reports is described in <http://cygwin.com/problems.html>.
