For me it's not the tables per se, it's the general proliferation of
options to get coverage on making things more error prone - the more
things always get seen by the compiler the better.  I'm not sure I care
enough to actually do the work but it's nice when someone has done it.

Anyway Thierry sent the #ifdef version of the patch so this is sorted
now.
