The library version will *probably* match the major version since we use
major version to indicate binary compatibility, which is what the lib
version also does. I'm just not entirely positive, though, so it is probably
best to keep the two numbers independent.

It should be quite easy for us to extract the lib version from a header file
(which would make it available to svn_ra.h for dynloading).

No can do. Windows does not use configure(.in), so you would end up defining
the version number in configure.in *and* svn_private_config.hw.

svn_version.h is the right place... that's why I put it there :-)

Agreed on the "one place". I think we probably want to introduce
SVN_VER_LIBRARY to contain the library version. We can then extract that for
use in the Makefile for building libs.
