[boost] [config] Why is BOOST_HAS_LONG_LONG defined in suffix.hpp?

The first few lines of suffix.hpp currently look like this:

#include <limits.h>
# if !defined(BOOST_HAS_LONG_LONG) 
      \
    && !defined(BOOST_MSVC) && !defined(__BORLANDC__)     \
    && (defined(ULLONG_MAX) || defined(ULONG_LONG_MAX) || 
defined(ULONGLONG_MAX))
#  define BOOST_HAS_LONG_LONG
#endif

What is the reason for this code being there? Isn't it enough to test for 
this in the platform/compiler/stdlib config?

I'm asking this question because currently stdlib/libstdcpp3.hpp 
explicitely turns off BOOST_HAS_LONG_LONG when the library indicates that 
there is no support for long long, and this is foiled by the code in 
suffix.hpp, which turns on BOOST_HAS_LONG_LONG again. (And this causes 
errors with gcc-3.3.x on Tru64.)

Maybe we need two config macros for this? One for 
BOOST_COMPILER_HAS_LONG_LONG, and one for BOOST_STDLIB_HAS_LONG_LONG?

Comments or thoughts, anyone?
