You started out asking about C but then finish asking about C++, which
are you asking about?

For C++ see https://stackoverflow.com/questions/46746878/is-it-safe-to-link-c17-c14-and-c11-objects/49119902#49119902

To the best of my knowledge the -std options for C do not affect ABI
either, but I'm less certain than I am for C++.
