Thanks,
Wouln't it be possible to only add the magic in boost/mpi/config.hpp ?
(which is supposed to be included everywhere in boost MPI)
Maybe something along the line of:
#ifdef BOOST_MSVC
#define _SCL_SECURE_NO_WARNINGS
#endif
?

Just out of curiosity (I do not have access Microsoft Compiler) what are these
warnings about ?
Ten years ago Microsoft identified C and C++ library functions that are prone
to security problems like buffer overruns (e.g. strcpy) and provided secure
alternatives. The compiler will warn you when you use an old, insecure
function. While this is in general not a bad idea it’s also inherently not
portable: https://msdn.microsoft.com/en-us/library/8ef0s5kh.aspx
Here is an example of a warning:
