I'd suggest we extend the documentation to say:

look for APR_USE_.*?_SERIALIZE

Anyway, those are *two* -- which is the default? The optimal thingy for this
platform of mine?

One is the default for cross-process mutexes while the other is the default
(and in fact only implementation) for intra-process mutexes.
.
I doubt that this geeky stuff from -V should really be pointed to by that
particular doc...

This is what it is referring to -- APR's default for the current platform.
-D APR_USE_SYSVSEM_SERIALIZE
-D APR_USE_PTHREAD_SERIALIZE
(Please don't say you want it in an understandable format :) )
Did I miss your point?
