DO NOT pre-defined __OBJC2__. The __OBJC2__ macro should only be defined when targeting the new, Apple 2.0 *runtime ABI*. It is not intended to be used to #ifdef ObjC 2.0 langauge features. This is unfortunate (given it's name). In a perfect world, this defined would be named __OBJC2_RUNTIME_ABI__. Oh well.

Neil pointed out that clang doesn't generate ranges from diagnostics
...
related to pp-expressions. Doing so is pretty simple and this
patch implements it, yielding nice diagnostics like:
t.c:2:7: error: division by zero in preprocessor expression
#if 1 / (0 + 0)
~ ^ ~~~~~~~
t.c:5:14: error: expected ')' in preprocessor expression
#if (412 + 42
~~~~~~~~^
t.c:5:5: error: to match this '('
#if (412 + 42
^
t.c:10:10: warning: left side of operator converted from negative value to unsigned: -42 to 18446744073709551574
#if (-42 + 0U) / -2
~~~ ^ ~~
t.c:10:16: warning: right side of operator converted from negative value to unsigned: -2 to 18446744073709551614
#if (-42 + 0U) / -2
~~~~~~~~~~ ^ ~~

clang.cpp: InitializePreprocessor now makes a copy of the contents of PredefinesBuffer and

Make a major restructuring of the clang tree: introduce a top-level
...
lib dir and move all the libraries into it. This follows the main
llvm tree, and allows the libraries to be built in parallel. The
top level now enforces that all the libs are built before Driver,
but we don't care what order the libs are built in. This speeds
up parallel builds, particularly incremental ones.
