Please check out the cygwin mailing list, where, within the last 24
hours, the topic of not sending personal email to the package
maintainers (specifically me) has been discussed.
Please do not CC or Bcc me on mail that is intended for the cygwin
mailing list. I read it quite regularly.
Anyway, to answer your question: I can't provide any advice. I don't
know how to do this.
