It happens at the end of AM_PROG_CC_STDC:

    case "x$am_cv_prog_cc_stdc" in
      x|xno) ;;
      *) CC="$CC $am_cv_prog_cc_stdc" ;;
    esac

Yes.  You also have to rename the cache variables.
It is probably a bit better to just make sure all the directories in
gdb use the same AM_PROG_CC_STDC macro -- use the newest one.
If you do this then it seems to me that it will be a little easier to
pick up future bug fixes.
