    _______________________________________________________

Details:

There's an extra line in commands.c that does...

#include <dlfcn.h>

This is not used in this file, and can be removed.

But it also causes build problems on platforms that don't have dlfcn.h as
well.

The code in load.c correctly wraps dlfcn.h because of the test and use of
MAKE_LOAD.

Therefore the one in commands.c can be removed.
