I managed to get 6.4.5-0 to compile on cygwin a couple days ago, and it kept
the orientation flag through a resize, at least for me and my couple of test
images.

This does sound slightly related to another bug I've been trying to keep an
eye on, related to convert stripping the Comment field. (described here:
http://www.imagemagick.org/discourse-server/viewtopic.php?f=1&t=11759  It
was said to be posed to the bugs forum, but I can't find it there)

According to my testing just now, even the other bug seems partly fixed;
sometimes I can get the comment to propagate, other times not.  (I had to
revise this email a couple of times as a result... inconsistent bugs are the
worst...)

Give 6.4.5-0 a try; it will probably fix the orientation problem for you.
