I'd hope it'd be the expected __STDC_VERSION__ >= 199901L for this 
check, but that ship may well have already sailed.

The compiler itself has been C99 since the ~millennium.

It's been the RTL and the headers that have lagged C99.

And as I've suggested before, I'd prefer to make the folks that don't 
want to update their code have to take some minor steps—setting some 
system parameter, tweaking a compiler CLD, defining some logical name 
(gag), whatever other LTS-enable scheme—to re-establish the old 
defaults for the old and unmodified compilations, and leave the 
defaults to be the most current compiler support available.  Drag this 
old mess forward best speed, and don't make those of us that are 
maintaining and updating our code pay extra and forever, versus not 
making the folks that aren't maintaining and updating pay even a little 
bit just once.
