Based on a brief glance, your patch looks OK, and with the
     #if (EPICS_REVISION = 14 && EPICS_MODIFICATION >= 11)
it should still work for previous releases, so why don't you commit that to
the repository.

The XML-RPC library used to be a compatibility problem, which is why I
included specific sources. One thing to watch for is that the sources
included with the archiver were patched to allow small numbers.

The XML-RPC standard didn't allow passing numbers in the "1e-10" notation,
only as "0.0000000001". But the original XML-RPC library used too few digits
when formatting numbers in to the protocol, so you got "0.000". I patched
that, but you'd have to check your later version to assert that it still
passes small numbers.

Thanks,
Kay
