One limited possibility is to use the Predef Check utility [1] to test
against BOOST_LANG_STDCPP. For example:

import path-to-predef-src/tools/check/predef
    : check require
    : predef-check predef-require ;

run csr_graph_test.cpp : : : : : <variant>release [ predef-require
"BOOST_LANG_STDCPP >= 41.3.1" ] ;

But I say limited because not many compilers will set the language predef
even if they support some particular C++11 feature you need. And depending
on the language feature you could also use the Boost Config check utility
[2].
