[Boost-users] conflicting intmax_t definitions - Boost 1.53 and gcc 4.8 incompatibility?

I recently upgraded to Ubuntu Trusty Tehr, and now the C++ project I'm
working on won't build.

It looks like the stdlib and Boost aren't working nicely together for some
reason. A bunch of typedefs are conflicting between the two, below is one of
the errors, where intmax_t is getting defined in two places. I'm not sure
what changed, but I now have gcc (Ubuntu/Linaro 4.8.2-14ubuntu2) 4.8.2 and
boost Version: 1.53.0.0ubuntu2

Here's an example error message:

/usr/include/inttypes.h:290:8: error: reference to ‘intmax_t’ is ambiguous
extern intmax_t imaxabs (intmax_t __n) __THROW __attribute__ ((__const__));

  typedef  ::boost::long_long_type            intmax_t;

Any help would be much appreciated. I'm fine with downgrading something, I'm
just not sure what to downgrade.... or if there's an actual fix, that's cool
too.
