long long is not supported by ISO C++03

Reported here: https://groups.google.com/forum/#!msg/thrust-users/jSujgymfbwM/MckpqfhvcFsJ

Can result in errors like:

/usr/local/cuda/include/thrust/detail/type_traits.h:464: error: ISO C++ does not support ‘long long’

Boost uses the following to check for long long

//
// look for long long by looking for the appropriate macros in <limits.h>.
// Note that we use limits.h rather than climits for maximal portability,
// remember that since these just declare a bunch of macros, there should be
// no namespace issues from this.
//
#if !defined(BOOST_HAS_LONG_LONG) && !defined(BOOST_NO_LONG_LONG)   && !defined(BOOST_MSVC) && !defined(__BORLANDC__)
# include <limits.h>
# if (defined(ULLONG_MAX) || defined(ULONG_LONG_MAX) || defined(ULONGLONG_MAX))
#   define BOOST_HAS_LONG_LONG
# else
#   define BOOST_NO_LONG_LONG
# endif
#endif

Thrust would probably have to do the same to fix this properly.

Thanks so much for looking into it, Filipe.

Now that I think about it, it's probably not worth addressing. The code in question has been there for years and we've just now heard our first complaint. The WAR is also simple (-Wno-long-long).

I'll leave it open for now.
