Given the versioning 'rules' (d: none) that apply to 0.9, I agree on 0.9 - not
sure I respect it on 1.2, but the problem is that they are data constants.  If
we deprecated these and REPLACED them that's a major screwup in binary compat
rules.  If someone wants to deprecate, they need to retain the existing binary
symbol and add the appropriate 'future compatibility' macro.

In any case, changing this would break compatibility, just like renaming the
libapr on win32 or netware to libapr-0 for 0.9, or libapr-1 for netware, so I'd
think we leave this alone.

Given that uptake of apr 1 has been slow (nothing that I am aware of until last
quarter of last year) I wouldn't take lack of feedback as confirmation ;-)

Fair enough by me, if someone wants them exported in 1.3, they should
adjust the headers to make this public.

Badda bing, badda boom.  Glad it's that trivial (as long as it's in the
list of functions.)

So I presume from your list that apr and aprutil build as a single dynamic
object in apr 0.9, and 1.x?  Could we get this right and split them when
apr 2.0 ships out?  Already, several projects use only apr, and don't wish
to have all the apr-util baggage.  [Of course, there's the broader discuss
to happen about splitting apr into dependency-related groupings, but that's
a topic for another day :-]

I'd really like to have the build for apr-util not depend on resource lists
in the apr repository, e.g. the need to add apu_version.h to a dependency list.
