I know people can use pre-processor conditional compilation based on

unsupported standard, but few people outside of library header authors
actually do that.  I'd really like :
 
    #pragma STDC VERSION C17
 
to force the compiler to use the equivalent of "-std=c17
-pedantic-errors" in gcc.

(I understand the wish to have that #pragma supported.)

Can there be linking problems when different "C" modules have
been compiled with different '-std=cXX' or '#pragma STDC ...'
settings? - The question just occurred to me.
