Comment (by jmroot):

 > I was never sure why the <cinttypes> switch seemed to work, TBH.

 The header in libstdc++ does this workaround for you:
 {{{
 // For 27.9.2/3 (see C99, Note 184)
 #if _GLIBCXX_HAVE_INTTYPES_H
 # ifndef __STDC_FORMAT_MACROS
 #  define _UNDEF__STDC_FORMAT_MACROS
 #  define __STDC_FORMAT_MACROS
 # endif
 # include <inttypes.h>
 # ifdef _UNDEF__STDC_FORMAT_MACROS
 #  undef __STDC_FORMAT_MACROS
 #  undef _UNDEF__STDC_FORMAT_MACROS
 # endif
 #endif
 }}}
 The one in libc++ just does a plain `#include <inttypes.h>`, which as it
 happens works fine on 10.7+.
