There is probably two potential culprits:

. Under cygwin, you have some mounts mounted in textmode.  This is bad.
  Check the all your mounts are in binmode.  If not, any cygwin-based
  compiled program that writes a line of text to a file, cygwin automatically
  addes a <CR> to get the <CR><LF> dos end-of-line format.

. With the Win32 version of Perl, extra <CR>s may be introduced since
  I think filehandles default to textmode and not binmode.

In the sample message page URLs you provided, if you look at the raw source,
extra <CR>s are getting added.  On many lines, there are 3 consectutive
<CR>s at the end of lines.

My hunch is you are mixing cyginw/unix-based tools with Win32 tools, and
the EOLs are gettings all screwed up.

If using cygwin and cygwin compiled programs, try sticking purely with
cygwin-based tools, including cygwin perl.  Also, make sure all mounts
are in binmode.  I have never seen a real need to have textmode mounts
with cygwin, and all they tend to do is cause problems like this.
