-questions, or maybe -hackers if it gets really complicated.

For shared memory, look at /usr/include/sys/shm.h. For semaphores, see
/usr/include/sys/sem.h.

There is a lot of documentation available on the FreeBSD website;
http://www.freebsd.org/docs/books.html 

In your case, the Developers' Handbook might come in handy.

It is also available on the system btw, in /usr/share/doc/en_US.ISO8859-1

I think that the glib library has this. It turns up a backtrace.h on my system.
There is no execinfo.h file on my system.

A quick search of the base system doesn't turn anything up. But
debuggers like gdb work, so there has to be a way to do it.

Nope.
