specifically, the widget binary uses header files that
claim to be MIT X11R4 with fix 10 installed and libXt.a
claims to be only MIT X11R3 or R4 with no fixes.

If it really is an R4 libXt.a then you're safe.  The only
way to turn off the message is to back out part of fix-10
and re-compile the widget(s).  Specifically, change XT_REVISION
back to 3 in IntrinsicP.h.
