Note we need to document (and configure test?) the build requirement for non-bootstrap and asan/ubsan bootstraps. For now we only document the requirement of a C++11 host compiler. Also not sure whether using -std=gnu++1y would allow more released compilers to build the code? For example GCC 4.8.5 knows -std=gnu++1y but not -std=gnu++14 and GCC 4.8.3 is required for bootstrap anyway. Richard. > Martin
