Ooops, didn't expect that. So my work was sort of redundant.

I've attached it. Has nothing to do with 64-bit support. Its purpose is
to allow RtAudio to open exactly as much input/output ports as were
specified on the ChucK command line. It also disables automatically
connecting these ports. Seems useful to me in any serious Jack setup
where you will need more than 2 or so output ports for ChucK and want
the connections be done by your Jack patchbay.
On the other hand you might want to be able to run ChucK without prior
patchbay setup. So I'm not sure whether this patch should just be
adopted. Perhaps only when a number of input/output channels are
explicitly requested this should be the default behaviour.

I didn't do that much. The first patch is new, the second patch is
largely Steven Sinclair's except "time/event => now" fixes and the third
patch is only a hack. Hope you can make use of it anyway. Will have a
look at your patch as well.
