I'm not sure it was the cygcheck.out that triggered the filter, especially
since most people have no problems in attaching a file named just that; it
could have been your choice of subject line, the use of HTML, or some
other problem.  However, you could try renaming the attachment
cygcheck.txt and see if that helps.

This has been discussed previously on the list, in January and February.
One option is for you to "#define readline rpl_readline" immediately after
including stdio.h, but before any use of readline in your package, so that
the two definitions don't conflict.  The other option is to upgrade to a
snapshot, including updated headers, where the cygwin getline is properly
guarded behind the _GNU_SOURCE feature test.

Changing system headers that don't belong to your package, in order to get
your package to compile, is usually a very risky effort that should not
normally be attempted.
