Meta key in cygwin

[Mattew Peavy <lists givemefish com>]

Hi all,

when using Windows, I appreciate having my MC nearby (via cygwin).  
However I don't get the "meta" key functionality from my left-of-space 
Alt key that I should.
When using other X-applications, this is not a problem (emacs, for 
example).  It seems to be particular to MC.
How can I achieve that functionality?

Thanks,
Matt.
