as well as the values given by gcc and clang to __STDC_VERSION__ in C11 mode.
We settled on requiring clang as well as LP64:
#ifdef __GNUC__
#if defined(__GXX_EXPERIMENTAL_CXX0X__) || (defined (__clang__) &&
defined(__LP64__))
#ifdef __LONG_LONG_MAX__
__extension__ typedef long long int rcpp_long_long_type;
__extension__ typedef unsigned long long int rcpp_ulong_long_type;
#define RCPP_HAS_LONG_LONG_TYPES
#endif
#endif
#endif
Seems to work for g++ and clang++.
