If you are using the boost sources via boost-build (use-project /boost :
/path/to/boost/sources ;), then it won¹t automatically make -mt suffixes,
but when threading is multi it will be multithreading safe.
If you are using the libraries installed by the system, you are probably
making lib rules with <name>boost_mpi. You could add the mt suffix or do
some magic so it picks the right one. I also made a Jamfile to auto detect
Note that if you use /boost//headers, to be compatible with 1_56 you need
to <use>/boost//headers <implicit-dependancy>/boost//headers. I need to
update the readme at some point.
Hope that helps!
