pdp++ cygwin xp

["Joshua W. Brown" <jwbrown@artsci.wustl.edu>]

Hi,

I'm trying to compile pdp++ for cygwin on Windows xp pro sp1.  I've followed 
the directions in Makefile.CYGWIN, but when I try to compile Interviews, the 
compilation exits with the following.  Can anyone point me in the right 
direction?  

Thanks
Josh Brown
