-------------------------------------+--------------------------------------
 Compiling a file.cpp with just 1 line:
 {{{
 #include <boost/chrono/time_point.hpp>
 }}}
 with a TI compiler fails with
 {{{
 error: the type of partial specialization template parameter constant "n1"
 depends on another template parameter
 }}}
 and similar errors in files: ratio/detail/mpl/gcd.hpp and lcm.hpp.

 Proposed workaround: mpl has a file mpl/aux_/config/dependent_nttp.hpp,
 which correctly #defines
 BOOST_MPL_CFG_NO_DEPENDENT_NONTYPE_PARAMETER_IN_PARTIAL_SPEC for this
 compiler. However, I couldn't find any place in boost, where this macro
 would be used.

 I've prepared a patch, that uses this macro to conditionally work around
 this problem.
