That's the same method I thought about in the first moment, but it
shouldn't work.  Gustaf says his Perl is cygwin's, so you'd have to use
cygwin notation:

     M-x shell-command-on-region RET perl /cygdrive/h/bin/ RET

....and even this works only if cygwin Perl is on your _Windows_ PATH.

Mixing cygwin with "native" Windows ports is always tedious and error
prone.  You always have to consider which system is going to expand
and evaluate path names, though PATH and cygwin mounts help a bit.

However, you can shell-command-on-region a .bat file from NTEmacs, so
perhaps the easiest workaround is to write a small .bat file that sets
up the cygwin environment (which e.g. honors #!) and then fires up the
perl script.
