As per Robert in the Crafty list, there were no changes other than that of the
egtb code. Maybe something else has changed.

No clue about the 19.19 buiness as well, unless these are changes Robert is
using and has yet to release.

The missing Crafty.c is easy to fix. Either create your own, or just drop the
one in from Crafty v19.17
