Yes, we don't use stuff that would break C99 compilers.  We have
macros or conditionally-compiled code when newer features are
desirable, but not supported by older compilers.  However, the amount
of such conditional code is very small, as the new features are
generally not important for what we need to do in Emacs.  And those
new features are very few anyway, since C is stable and rarely if ever
changes in significant ways.
