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?

Certainly.

#include <stdio.h>
main(void) /* C99 removes implicit int */
{
int restrict = 5; /* restrict and inline are new keywords */
int inline = 10 //*
/* subtle effect of "//" comments */
restrict;
printf("inline = %d\n", inline);
return; /* C99 requires return <expr> for a non-void function */
}

We must do something. This is something. Therefore, we must do this.
