Incorrect usage of `long long` in Boost.Intrusive

[Antony Polukhin]

boost/intrusive/detail/utilities.hpp uses long long even on C++03/C++98 compilers, which do not have support that type:

Those uses are protected with BOOST_HAS_LONG_LONG, so I don't understand why is this macro active when compiling in strict ISO 98 mode. Maybe you are activating some -Wno-long-long and compiling warnings as errors? I don't think there is a fix for this, unless boost/config is modified to detect long long warning as error was activated by command line.

Replying to igaztanaga:

You're right. I've become over pedantic and compiled code with -Wlong-long

(In [85684]) Do not treat long long warnings as errors in lexical_cast + containers tests (fixes #9061)
