You could configure different install and search paths for single- and
double-precision versions of Pd. I don't know if they share the config
file. If they do, you would have to adjust the config whenever you
switch between them.

Just compile it against the m_pd.h of the double-precision edition of
Pd. That's not a very qualified statement, though. I haven't tried it
myself yet. And from what I read about the topic, not all sources are
compatible with Pd64 right away.
