Re: So what Standard are we working off?

Is there a case where a correct C90 program cannot be successfully
compiled by a C99 compiler? Actually this is not a compiler question but
a language one. Is there anything in C90 that C99 must reject or handle
differently?

Yes. Consider the new "inline" and "restrict" keywords, the
dropping of implicit int, and the disallowing of implicit
function declarations.
