OK, I was getting this about 4 days ago, but I assumed I caused it so I
went off and played with some other things for a while before coming
back to it. When I do the following I get the other following behavior
in GCC debugging Apache. I am using the latest Apache from CVS as per
Greg's comments re the mod_dav changes.
My first notice was the DB_VER=3 deal, but then I figured out that it
was using DB_VER=3 for both 3 and 4 of DB so that wasn't what was
happening.
