It seems to me that we have very specific information about a certain
libc's requirements but we're ashamed to admit it and so we're
dressing it up in autoconf for political correctness. Unfortunately,
the resulting code risks turning on unnecessary or undesirable
ower for all production uses.

I think you need to be very explicit about what you see that you don't

It would seem that for the lock operations supported by APR there is a
platform-independent interface for the application to use. I
sometimes think it is missing some cool stuff but that is another
issue.

If APR has the code to back down to the default then there has to be a
special return code from apr_lock_create() to indicate that the app
got the default and/or some other way for the app to find out that it

Currently, we think APR_HAS_SYSVSEM_SERIALIZE if the platform has
semget() and semctl().
What is in your apr/include/arch/unix/apr_private.h for HAVE_SEMGET
and HAVE_SEMCTL?
Can you grep through the Darwin header files for the related
declarations (struct sembuf, IPC_PRIVATE, etc.)? Maybe they are in a
header file which isn't included from crossproc.c?

Note that APR currently doesn't have the right information now to set

What sort of problem are you hitting with apr-util coming first?
