I have build Mutt 1.1.4 with CygWin B20.1 (using ncurses 5.0).  However
the pager acts funny: when scrolling down past the end of the message
sometimes I see a little garbage and then the contents of another message
(probably the next one -- with full headers), and sometimes Mutt gets a
SIGSEGV.  CygWin produces a `core' file that is pretty useless (IMHO),
but I'm attaching it anyway, just for sake of completness.

Now gdb isn't fun under CygWin (it messes stty settings 9 times out of
10), but somehow I managed to get a stack trace.  *attach*
(Offtopic: what is the canonical ASCII representation of the sound of
attaching a file? ;-)

The crash occurs in resolve_color (pager.c line 222).  I've tried
removing all `color' directives from .muttrc, just in case.  That didn't
help at all.
