In Hopper, we added a call to a motif function defined in a private header file.
We should try to avoid this dependence.

Below is an excerpt from one of the emails on this subject.


RVSM> In the J2SDK 1.4.1 bl11 drop, Sun modified function MyClipNavigable(), in file
RVSM> j2se/src/solaris/native/sun/awt/awt_ScrollPane.c, to call XmIsClipWindow().

RVSM> Where is XmIsClipWindow() defined ? It does not appear to be part of the Tru64
RVSM> UNIX Motif set of interfaces.

Motif 2.1.0, OpenMotif 2.2.3:
ClipWindowP.h:#ifndef XmIsClipWindow
ClipWindowP.h:#define XmIsClipWindow(w) (XtIsSubclass (w, xmClipWindowWidgetClass))
XmP.h:#undef XmIsClipWindow
XmP.h:#define XmIsClipWindow(w) (_XmIsFastSubclass(XtClass(w), XmCLIP_WINDOW_BIT))
