This doesn't build on 32 bits:

selftest.c: In function ‘void run_self_tests()’:
selftest.c:62:27: error: format ‘%lu’ expects argument of type ‘long 
unsigned int’, but argument 2 has type ‘std::vector<void 
(*)()>::size_type {aka unsigned int}’ [-Werror=format=]
       tests.size (), failed);
                            ^
I think the right format size specifier would be 'z'.
