X11 Question

[Alex Rzasa]

Dear All,

I am a newbie and would really appreciate someone's help.  When I try to
'make' on an uncompressed tarball in cygwin I get this message:

gcc    -c psdriver.c -o CYGWIN_NT-5.0/psdriver.o
psdriver.c:56: X11/X.h: No such file or directory
psdriver.c:57: X11/Xlib.h: No such file or directory
psdriver.c:58: X11/Xatom.h: No such file or directory
psdriver.c:59: X11/Xutil.h: No such file or directory
make: *** [CYGWIN_NT-5.0/psdriver.o] Error 1

Does anyone know how to fix this?  I have these files; they're under
/usr/X11R6/include/X11/, which I added to the path in /etc/profile but it
still gives the same error.  Thanks for your time,

-Alex
