Andrew,
I can't compile OvmfPkg with XCLANG (OSX 10.7.5, Xcode 4.4.1 + CLT 4.5.2)
---------------
Building ... /Users/Sergey/src/edk2/OvmfPkg/AcpiTables/AcpiTables.inf [X64]
ld: warning: -macosx_version_min not specificed, assuming 10.6

Error 1
---------------
What is wrong? It works fine with GCC47.
