[LLVMdev] FreeBSD Support In lib/System

[Jeff Cohen]

My experiment to build as if Linux has failed:

What I don't understand is that the assert macro is used all over the
place, so why is it undeclared only here?  It is declared in assert.h on
FreeBSD, but there is not a single include for it I can find other than
lib/System/Unix/Unix.h, and I'm not using "Unix" platform.

I'll start over and use Unix.  It won't be until Friday before I have
results.
