Righty.  That was what the LLVM_CLANG_ bit was for, but an extra _ won't
hurt.  :)

Gotcha, will do.

I was wondering about that.  How about std/c/ ?  Later on one could add
std/objc/, std/cxx/, etc as needed.

I was also wondering where these headers should be installed.  GCC puts
them in its own private target-specific path, but we're not doing the
target-specific header stuff.  Would $(prefix)/include/llvm/std/c/ be
acceptable, or what?
