This topic needs a title

I'm trying to link xgrass, having gotten the various sources to compile,
and I'm having a problem with an external reference in libes/Xgi/Help.c.
The reference is to a function:

_XtGetCallbackList

which I don't find in any of my libraries or Xt docs or headers. There
should be a workaround involving working through the Widget structure;
but, I'm not an X programmer, and I would rather not mess with this if
someone already knows what to do.

I'm working on a Data General AViiON, with system 5.4R2.01.

Thanks for any help on this matter,
