I have found that
boost::uint_t<64>::fast
gives a compiler error even on a platform (RH 7.3 on Intel) that has
64-bit integers available (as long long). On checking the documentation
again, it does specify this behavior, but this strikes me as quite
unreasonable; if a platform has long long, I should be able to use it.
I believe that all that is needed to fix this is inclusion of the
following lines:
#ifdef BOOST_HAS_LONG_LONG
template <> struct int_least_helper<0>
{ typedef long long least; };
#endif
#ifdef BOOST_HAS_LONG_LONG
template <> struct int_least_helper<5>
{ typedef unsigned long long least; };
#endif
Also, I'd like to see the following added to <boost/integer.hpp>:
boost::signed_int<T>::type -- Gives the signed integer type of the same
size as integer type T.
boost::unsigned_int<T>::type -- Gives the unsigned integer type of the
same size as integer type T.
Rationale: I often find myself using
std::iterator_traits<Iterator>::difference_type
for quantities that are guaranteed to be nonnegative; for these I would
prefer to use an unsigned type.
