The obstacle is that we support building OpenLDAP with C90 compilers.

If we ditch that and require a C99 compiler, we can kill annoyances like
Debug() extra args.  IIRC the answer has been "sigh, not yet" for a long
time, I don't remember if it still was last time we talked about it.

(We can still have headers which support C90, so people only need C99
for building.)
