There isn't. This is specific to the HP-UX client. Your svnserve
platform doesn't
enter into it.

Irrelevant.

This is what matters. I assume you downloaded that sucker (lemon drop?) from
http://hpux.connect.org.uk/hppd/hpux/Development/Tools/subversion-1.3.1/
and figured, hey, it's from HP, semi-supported, what could possibly go wrong...?

Yeah, me too. Ended up wiping and recreating the hp build user, and used a
different (and accidentally short enough) password, and resigned myself to a
head scratching "Huh!" with regard to the now-vanished problem. Until I went
and made everyone upgrade to 1.4.x - including all of my build-daemons. In
the process, I had to fix a compile failure on the HP-UX 11.23 (IA-64) version
because to EDG front-end (B.06.12) tripped over a bad hp header file. The
old nagging puzzle turned into an "A-hah!" and, shortly, correctly functioning
builds on both HP-UX 11.11 (PA-RISC) and HP-UX 11.23 (IA-64).

Don't feel too bad about not attributing the culprit here. My team and I have
had a few encounters with massive flaws in HP-UX (OS, libraries, and compilers)
manifesting in production releases of an enterprise-level data
management server.

Eventually you get to the point where you just want to blame everything on
that massive PoS platform, unless the bugs show up on another OS.

A-yup, dat's der bunny.

It would, if it hadn't gotten fsck'd internally by his client.
