[PD] Successfully compiled Mac OS X Intel externals

[Stefano Papetti]

Hi,

I'm sorry but at present time our MacBook is away so I can't try it out.

I'd like to build universal binaries in the near future but I have to
study Apple's documentation about them... It should be pretty simple:
compile 2 kind of file object (one with the -arch i386 flag and the other
with ppc) and them merge them at linking time. If I'm not wrong, the
makefiles provided with Pd 0.40 for Mac OS X 10.4, do exactly that.

Best,
Stefano
