the CSound Language

I would like some help understanding the CSound API for C++, i can't seem to compile it on Visual Studio 2008/9, a couple of odd problems stdint.h doesn't exist and after i add it, two redefinition errors.

Anyone used CSound before? (I'm writting a synth engine btw)

x86-64 has a common floating point instruction set (SSE2) as well.

ARM doesn't even have a 64-bit mode yet!
and yet an ARM processor is a lot faster at 64-bit integer operations than an x86-64 processor using the same amount of power.
