I gave it a whirl on OSX Mavericks, Xcode 5.1
Apple LLVM version 5.1 (clang-503.0.38) (based on LLVM 3.4svn)

a.cc contains only:
#include <stdlib.h>

$ ./warpdrive_clang3_4 -I /usr/include a.cc >~/a.pp
/usr/include/stdlib.h(92) : identifier expected after 'defined'

#if !__DARWIN_NO_LONG_LONG <-- line 92
typedef struct {
	long long quot;
	long long rem;
} lldiv_t;
#endif /* !__DARWIN_NO_LONG_LONG */
