I guess the author will have to confirm, but #! behavior is something built in
to the system calls in Unix, and is likely provided in a little bit different
manner under cygwin.  I am not sure what run.exe would have to do to make it
happen -- maybe add its own functionality to look for and parse a #! line.

Sorry, no -- I think I have seen that myself some in the past.  The
author/maintainer of run.exe will probably have to answer these.

By the way, you could create a copy of run.exe called runperl.exe (or maybe
just a link with that name) and it will run perl, as documented in the man
page for run.
