The intent is that my_reportAmbiguity be able to duplicate the
functionality of yyreportAmbiguity, so it would be passed
yyreportTree as a call back.  The other parameters being those
passed to yyreportAmbiguity.

Of course developers could choose to print, or not, the tree in
their own way, but they would have to export the necessary information.

This is the bit I am tempted to have a go at.  Stopping things
happening is probably easier than making them happen.
