Introduce <Xm/XmPrivate.h>

We need ANSI C prototypes of certain Motif
functions that are not published in the official
header files.

<Xm/XmPrivate.h> header file contains
the prototypes extracted from the Motif source.

To re-create <Xm/XmPrivate.h>:

1) Make sure you have sources of libXm
(lib/Xm directory of the Motif distribution)
accessible via imports/motif/lib/Xm

2) rm include/Xm/XmPrivate.h

3) make includes

cde/include/Xm/Imakefile
