[pypy-dev] PyPy under FreeBSD 7

PyPy is currently building on my FreeBSD 7 with no problem at the moment.
I'll be able to tell more later. I had to modify a few files and create a
new platform to specify some include/lib paths. I'll have to see with you
Marciej on the best way to integrate that. About "errno", FreeBSD 7 does it
the Darwin way, probably to be POSIX compliant. Else, there are a few
includes that have to be added and some lib incudes that have to be removed
in order to pass the platform_check part. As I write these lines, the
translation just failed with the following trace:
