Also note that these headers will be different from one operating system to the next.  If you're looking for something portable, test out my wrapper at http://sourceforge.net/projects/llvmlibc/ in the SVN repo.

Clang's PCH format is Clang AST bitcode, not LLVM bitcode.  If we stored PCH as LLVM IR we'd lose enormous amounts of information even from C, and Objective C and C++ would be completely impossible.

They use the same binary-stream library, but that's where the similarities end.
