Indeed that is enough for Automake's current needs.  But that hook is
currently in AC_PROG_CC, while Nick's proposal involved having something
like that in AC_PROG_CC_C_O, for which AM_PROG_CC_C_O would continue to
be a thin wrapper (but automatically invoked by AC_CONFIG_COMMANDS_PRE
whenever needed).
