Just to be clear: such a Frankenstein setup is utterly unsupported.

If that machine really can't be upgraded properly, a better approach
might have been to install Cygwin 1.5 alongside 1.7 on your
development machine, by pointing at
a different base directory, and use that to build your program before
moving it across. Or just build it on the other machine in the first
place. (This is assuming you've got the source of course.)

Cygwin 1.5 of course is now also unsupported, but at least it's proven itself.
