I got. Since no anybody more has commented, let us be sure that the mask mechanism has gone. [I've recently found corresponding bit mask in gcc-3.3.6 in grokdeclarator (c-decl.c), e.g: > 3589 if (i == RID_LONG && (specbits & (1 << (int) RID_LONG))) or > 3624 specbits |= 1 << (int) i; where > 3586 enum rid i = C_RID_CODE (id); ] So for the sake of those who will develop C-derived front ends, should we change the comment like below: > /* Reserved identifiers.
