We require a C99 *compiler*. That's a different thing from assuming
that the contents of /usr/include are C99-compliant.
Admittedly, the days of user-installed copies of gcc being used with
crufty vendor-supplied system headers might be over for most people.
But my animal gaur still has such a configuration, and it hasn't
got stdint.h at all, never mind any particular contents thereof.
