Block.h/Block_private.h headers, since clients won't know what to set. These are moved into runtime.c as appropriate 2) Use cmake checks for CAS builtins, instead of guessing based on GCC #defines (which aren't set by clang and llvm-gcc anyway) 3) "#pragma mark" isn't supported by FSF gcc, so "#if 0" it out. It should still show up in IDEs that support it 4) Fix some compiler warnings. GCC 4.3.3 seems super strict about %p. function pointers can't be cast to void * either. 5) Avoid a warning for apple_versioning.c that "ISO C does not allow empty files" llvm-svn: 82504
