There is a so-called environment iterator in Boost.ProgramOptions (see  
<http://www.boost.org/doc/libs/1_58_0/doc/html/boost/environment_iterator.html>).  
And the library that should have become Boost.Process has support for  
passing environment variables to a new process (including std::wstring;  
see  
<http://www.highscore.de/boost/process0.5/boost_process/tutorial.html#boost_process.tutorial.inheriting_environment_variables>).
