FIX was Re: Cygwin Failure on multiple targets

[Joel Sherrill]

I hate to reply to my own posts but I tripped across the fix
and I had seen it before. :(

LIB was being inherited from Windows and pointed to the 
wrong place for Cygwin.

INCLUDE was also being inherited from Windows and I assume it
could eventually cause problems as well. 

I added "unset's" of both variables to the .bashrc.
