I was, shall we say, a little out of the loop on 3.1 development ;-). 
The 3.1 Unix-specific files (e.g. config.h) neglect to redefine these. 
Thus, the Unix version of 3.1 reverts to the defaults defined in
frame.h.  I'm not sure that's a problem, since the Unix version has no
need for UI callbacks at this stage.  Note, however, that the defaults
_are_ in frame.h in the Unix source.
