Hi Microsofters,

I have a problem when compiling C code for more than 2 weeks to catch whether /experimental:c11atomics is set for msvc inside code. I tried checking for __STDC_NO_ATOMICS__ macro but in vain. Could anyone please give me any tip how to check for that?

Thanks a lot in advance :)

    Hi, @Adam Satko

    According to the blog:

    Note that we still define __STDC_NO_ATOMICS__ so if your build system is testing for that you will need to add a special case or change to checking if compiling a translation unit including <stdatomic.h> succeeds.
