One thing that stands out on the Mac OS X front is the fact that Pd
is using the double precision math functions even though Pd uses
single precision floats. You can see it here:
Here's a previous discussion on this:
I don't think this would make a massive difference overall, but I'll
bet it would make a significant difference for any patch using sin,
cos, atan, atan2, sqrt, log, exp, fabs, or pow. Anyone feel like
writing a patch to make ./configure set things up properly?
