It's this "in recent VisualStudio" that worries me.  So C99 support was
lacking for many years, and even now some things are "optional".

Users may be stuck with an older compiler for many reasons.  Sticking
with C89 is putting the level too low, but requiring a full C99 compiler
is too much.

We cannot rely on all compilers to support all C99 features.
We will have to pick the ones that we can use.

I'll make some patches to introduce C99 features, so that we can check
what actually works.
