Alex,

Please make sure your mailer respects the Reply-To header -- I set it for
a reason.  Also, <http://cygwin.com/acronyms/#PCYMTNQREAIYR>.  Thanks.

Secondly, asking people to help you use Cygwin to later use a "competing"
product is bordering off-topic for this list.  However, I would be
surprised if the Linux kernel didn't build in the ksh environment.  Unless
the configure scripts contain some bash-isms, it should just work.
	Igor
