Well, XOR is contained in the C++ interface, see
rt^3/include/brlcad/Combination.h.  Removing "ExclusiveOr" there would
change the index of "Leaf" and produce incompatible versions of the
brlcad.dll.  Or I could leave a dummy entry there, ...

Want excitement?
Manually upgrade your production database.
When you want reliability, choose Perforce.
Perforce version control. Predictably reliable.
