Where's this Windows path coming from?  Are you sure you're using only
Cygwin tools?  If so, get rid of the Win32 path and use either the
matching /cygdrive path, or mount (the relevant subtree of) drive J to
some other POSIX path.

The permission denied is probably not the permission of sh itself, but
the permissions of the script.  It's lacking execute permissions,
perhaps.  If the script gets generated during the make run, it might
be a race.  One job tries to use the script before another job has
run chmod on the script.

Instead of building your own debug version of Cygwin, you could also
just start with stracing your make runs and see what happens when the
script access fails.
