This hasn't got much to do with GregH's change, but ...

Could someone enlighten me as to why we're explicitly casting a void*
to a char* here? I also see

    memcpy (start_address, (void *) bytes, count);

later on in the same file. I thought we were using ANSI C, and
-Wmissing-prototypes, so why the cast? The only effect of such
casts is that they hide potential bugs the compiler might warn
about. I'd go as far as adding a note to the HACKING file that
Subversion code should have no typecasts whatsoever, except where
necessary for interfacing with foreign libraries.
