For that to work, MSVCRT__register_onexit_function and MSVCRT__execute_onexit_table have to available all the time, not only when _MSVCR_VER>=140

Hi,
While running your changed tests on Windows, I think I found new failures. Being a bot and all I'm not very good at pattern recognition, so I might be wrong, but could you please double-check? Full results can be found at https://testbot.winehq.org/JobDetails.pl?Key=39191
Your paranoid android.
