No, "-Duseperlio" is now default for Configure in perl-5.9, and -Uuseperlio is
unofficially unsupported

I've bugged Schwern with such long time ago, but he didn't see where. So if
you can supply the patch, I guess he would be willing to apply :)

cygwin != win32. If you install cygwin in binmode, it should emulate `real'
unix, so hoop-jumps /should/ not be needed.

again, cygwin != win32, and let's hope it stays that way.

agree

Can you try Yitzchak's patch:

+++ perl/lib/CGI.pm	Wed Feb 19 13:35:50 2003

If that is OK, I'll submit. [ I've got no time currently to test myself ]
