Maybe, can you provide a test case please (or supply a modified version of
the existing test in libs/config/test/boost_no_mem_tem_keyword.cxx).

BTW, I think several existing compilers choke when you try to put multiple
scope operators in the one typedef, for example the existing test splits a
typedefs like this up:

typedef typename ifoo::template nested<double> bound_t;
typedef typename bound_t::other other;

Whether that's the issue here I don't know.
Thanks,

John.
