rdesktop not finding X libs

["jose isaias cabrera" <jicman at cinops dot xerox dot com>]

Greetings!

I am trying to build rdesktop with cygwin.  (I have done this a week ago 
with my computer at work.)  However, I am running into problems with my home 
computer: it's not finding the X libraries, even though they are there.  I 
have uninstalled cygwin and reinstalled it back with the same libraries and 
I still have the same problem.  Here is a run capture of ./configure

So, how can I fix it?  Again, I really don't know where to go from here, but 
apparently, cygwin's setup utility is not updating the libraries as it 
should.

Any ideas?

thanks,
