Are you sure you want "-I/usr/openwin/share/include" instead of
"-L/usr/openwin/share/include" ?

Where are libX11.aand libXutil.a on your system?

In my experience, Sun Unix platforms put them in "/usr/openwin",
while most other -nix platforms put them (or at least links to them)
in /usr/lib or /usr/X11R6.

You need to find where thosw libraries are on your system, and
set the "-L" options appropriately to point to them.

Line 15 of your source code apparently references a function
named "create_int_directory_entry" without you having provided
a prototype for that function.

Ditto for these warnings.

libXlib.a and libXutil.a could not be found in the paths you provided.
