Yes.  And this has come up on the lists before.  The short answer is that
it is unacceptable to pop up a modal dialog box when executing a
non-interactive shell script, so cygwin intentionally requests Windows to
not pop up the dialog.  At which point, all you are left with in the case
of a missing .dll dependency, is cygwin interpreting the Windows error
exit status, which turns out to be status 53.
