It has stripped history and merged with OpenLDAP/mdb.master, because
mdb.RE/0.9 don't includes a few critical fixes (ITS 7969,7970,7971) for our
case.
I think that is the reason for patch conflicts.
Patchset got RE25 should remain among my sent emails. Presumably I can send
it for you again, if you are interested.

IMHO the Log<N> recipe is onerously for support.
On other hand, nowadays all non-obsolete compilers support most of C99
features.
Baseline features, such as "variadic macro", supported long ago (Microsoft
was the most conservative to 2012).
Maybe it is time to enable C99 in RE25?
