Windows? I don't know the status of the most recent MSVC compilers, but they
haven't been c99 compliant in the past and compliance doesn't seem to be a
priority. Other compilers are a mixed bag. This is the git conundrum:
support isn't sufficiently widespread on all platforms to make the
transition so we are stuck with the lowest common denominator.
