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".
