In the future, please post to the Cygwin mailing list instead of sending
private email so others can benefit too.  This is especially true after an
email such as the following:

Hmm...

Anyway, on to your most recent problem.

Does the script start with "#! /bin/sh"?  If so, then your problem is
that ash (i.e., /bin/sh under Cygwin) does not support "let".

The above works because bash is processing the script instead of ash
even if it contains the "#! /bin/sh" trigger line.

Not true, other keywords such as "for" are recognized by ash -- just not
"let" (and possibly other bash keywords).

This is standard Cygwin ash behavior and IMO, is not a problem.
