However, it should generally not try to distinguish between bug-fix 
variants of the same standard version (such as the 2011 and 2018 editions 
of ISO C, or the 2008, 2013, 2016 and 2018 editions of POSIX).  (There may 
be rare exceptions, e.g. where some interface was marked obsolescent in a 
bug-fix revision, as was the case with ATOMIC_VAR_INIT in the 2018 edition 
of ISO C.)
