I will consider this fix in the next Pod-Parser release.

Cygwin & Perl:
This issue is still present.
Reini's PERLIO suggestion functions as a work-around on Cygwin.
Who decides if/when to use Reini's suggested patch? If that decision
has already been made in the negative, why and what is the next step?
If that decision has already be made in the positive, when will we see
the correction in Cygwin?

pod-people & perlbug:
I made the subject posting on the Cygwin mailing list. Gerrit P.

confirmed the bug in pod2usage(), and requested that I forward the
posting to
pod-people and perlbug. The referenced script attachments follow.
All three cases work fine for me on cygwin & perl 5.8.6 with default
configuration.
Having the scripts on textmounts and on binmounts.
Just if the scripts are on textmounts and the files with CRLF, test0 and
test1 will fail. PERLIO not set.
However:
PERLIO=crlf ./test1
and
PERLIO=crlf ./test0
works ok, with those textmount cases.
Debugging through Pod::Usage, reveils that reading from the tied
FileHandle will keep \r\n. Looks ok.
Pod::Parser::parse_from_filehandle ...
DB<1> x $in_fh
0 GLOB(0x8f2534)
-> *Symbol::GEN0
FileHandle({*Symbol::GEN0}) => fileno(6)
DB<2> c Pod::Select::is_selected
Pod::Select::is_selected(/usr/lib/perl5/5.8/Pod/Select.pm:508):
$_ = "=head1 SYNOPSIS\cM\cJ\cM\cJ";
if (/^=((?:sub)*)(?:head(?:ing)?|sec(?:tion)?)(\d*)\s+(.*)\s*$/) {
my ($level, $heading) = ($2, $3);
}
DB<2> x $heading
0 "SYNOPSIS\cM"
Which should be "SYNOPSIS".
So my recommended fix would be this patch:

Subject: Cygwin Perl bug -- pod2usage(-verbose => 0) &
pod2usage(-verbose => 1)
Cygwin:
Perl Pod::Usage pod2usage(-verbose => 0) is supposed to display the
Pod SYNOPSIS
information (ref. 'perdoc Pod::Usage'). See attached script 'test0'.
On Debian
3.0r2, it works:
<CVSENV>[EMAIL PROTECTED]:~/cygwin-issues/Pod-Usage$ perl test0
Usage:
This is the synopsis...
On Cygwin, it exits without displaying anything.
pod2usage(-verbose => 1) is supposed to display the Pod SYNOPSIS,
OPTIONS,
ARGUMENTS, and/or OPTIONS AND ARGUMENTS sections. See attached script
'test1'.
On Debian, it works:
<CVSENV>[EMAIL PROTECTED]:~/cygwin-issues/Pod-Usage$ perl test1
Usage:
This is the synopsis...
Options:
Here are the options...
On Cygwin, it exits without displaying anything.
pod2usage(-verbose => 2) is supposed to display the entire Pod
documentation.
See attached script 'test2'. It works on both Debian and Cygwin.
Checking the mailing list archive, I see one report but no resolution:
http://sources.redhat.com/ml/cygwin/2002-01/msg01392.html
Google didn't seem to have much on this either.
