Subject: AVX on OSX

Finally I managed to build on OSX with -march=native, enabling AVX and stuff (until now you could only get SSE2).

The problem is two-fold. First you need to get a real, recent gcc. This is easy, for example you can get one from Homebrew or Macports. Second, you need an 'as' that is capable of AVX and stuff. This is harder but today I found an ingenious script[1] that make 'as' a wrapper to clang's assembler, which do understand the new instructions (even the native clang does).

The script is included in the commit. To use it, you need to copy it (osx_as_wrapper.sh in the src directory) to /usr/local/bin/as or to some other directory (but the file MUST be named 'as') and ensure this directory is first in your $PATH. And before you ask: No, this can't be done with $(AS) in Makefile no matter how you put it.
