Peter was talking about apr-0 and apr-1 coexisting there, to which this
*is* irrelevant but if the real issue is making the differently-linked
*subversion* packages coexist, I see the relevance. I guess it vaguely
makes sense to do this soname munging upstream for that reason; but
certainly it must be done based on the APR major version not the
apr_off_t size, which is merely one aspect of the APR ABI. And also the
APR-util major version if you want to be pedantic, per previous mail.

But doing this now in a 1.x release *by default* would be very
unpleasant; having a special "make my sonames Debian ABI policy
compatible" configure option seems somewhat perverse.
