Modified: src/include ap_mmn.h
Log:
ap_log_rerror() certainly wasn't a minor change, it happened before that
concept existed. Put its correct entry into the list.
Make the minor module number useable... provide a macro that tests the
version in a more convenient mannor.
Add ap_overlap_tables() (which I'm about to commit).
