Maciej, thanks for having a look.  The current code builds on 32-bit but goes into a loop and crashes when vadd() calls back into itself recursively because of a macro which is defined only in the __ppc__ and __i386__ case.  The vDSP_translate.h file defines these macros, but only gets included in the 32-bit case. 

Even though my vadd() and vsmul() functions are in a namespace, the macro screws things up, and it seems unfortunate that Accelerate.h is defining these kinds of macros.

The ARM case should be OK, since I'm using exactly the same compile-time conditional as the framework is using.
