the function XmVaCreateSimpleCheckBox() is broken. It should work like
XmVaCreateSimpleRadioBox() with
XtVaSetValues(radio_box,XmNradioBehavior, FALSE,NULL);
but produces nothing. example code is attached.

Note: I reported to bug to devuan already but was ask to report to
debian, as this is not a fork and we were both unable to report the bug
to upstream bug tracker (http://bugs.motifzone.net).
