Problem with X11 include files

[jblazi]

I am trying to compile a small application from the GUILE tutorial. This
application needs X11/Xlib.h. I installed the X11 files and the include
file is in the directory d:/cygwin/usr/X11R6/include/X11, but I do not
know how to tell this gcc. For example

$ gcc -I/d:cygwin/usr/X11R6/include/ tortoise.cpp -o tortoise
tortoise.cpp:1:22: X11/Xlib.h: No such file or directory

does not work and if I specify the full path in my application then the =
include files Xlib.h needs, are still not found.

Any hints?

TIA,
