I tried to do more debugging, but I got lost in what calls what with the
3D board rendering.  However, one additional, potentially useful piece of
information: I annotated board3d/drawboard3d.c:drawPieces thusly:

        if (bd->DragTargetHelp)
        {       /* highlight target points */
                glPolygonMode(GL_FRONT, GL_LINE);
                SetColour3d(0.f, 1.f, 0.f, 0.f);        /* Nice bright green... 
*/

/* =====> */    printf("Displaying target help points\n");
                for (i = 0; i <= 3; i++)
                {
                        int target = bd->iTargetHelpPoints[i];
                        if (target != -1)
                        {       /* Make sure texturing is disabled */
                                if (prd->ChequerMat[0].pTexture)
                                        glDisable(GL_TEXTURE_2D);
                                drawPiece(bd3d->pieceList, bd3d, (unsigned 
int)target, Abs(bd->points[target]) + 1, TRUE);
                        }
                }
                glPolygonMode(GL_FRONT, GL_FILL);
        }

and that printf statement is never called in my build.  So something is
either failing to set DragTargetHelp or iTargetHelpPoints or drawPieces is
never called while a move is in progress.  This seems to apply with either
quick-draw turned off or turned on.

I don't understand why I would be the only one seeing this, though.

Target help works fine with a 2D board.

I tried to use gdb to figure out why those variables aren't being set, but
it's very difficult to use gdb with gnubg and not have it lock up the X
server when one is trying to do it all on the same system.
