That probably means what it says: that the object code of these files
have been compiled by a version of GNAT different from what you are using.
Try recompiling them.

On old versions of windows, that use autoexec.bat, add the lines
set ADA_INCLUDE_PATH=<your path here>
set ADA_OBJECTS_PATH=<your path here>

On newer versions select 'My Computer', click on properties, go to the
advanced tab en press the 'Environment variables' button.

With gnatreg you can tell the compiler where to find files using the
registry instead of environment variables. Run it for more info.

You migh be better off using the Sockets library that is included with
GNAT. See the Reference Manual under 'The GNAT library'.
