sorry, just thinking back to discussions several years ago.

even within a typical libc there are at least two error mechanisms --
errno/strerror(), herrno/hstrerror().  if you're using glibc then you've
also got gdbm_error/gdbm_strerror().  if you use zlib theres an error with
each file handle and gzerror() to get the string.  the list goes on.

btw, an alternative to trying to define an exception mechanism for C
(which i *think* you'll end up if you continue thinking about this) is to
combine apr and apr-util into one library so they can just do their
"registering" at compile time :)
