in reply to What? I patched Perl?

As for submitting the patch, P5P (the Perl5-Porters) prefer patches in "universal diff" format (diff -u OLD NEW).

And if you (like me) don't have the 'u' option (or diff for that matter), grab gnu diff from http://www.gnu.org/directory/diffutils.html (or elsewhere for binaries).

Update: On Win32, at least get get UnxUtils, if not Cygwin.
