Using Common for Wdate-time when it is defined in c.opt does not really make sense and breaks CPP(). I also took the opportunity to move a duplicated testcase to c-c++-common. (svn diff does not show the move). Bootstrapped and regression tested on x86_64-linux-gnu. OK? gcc/c-family/ChangeLog: 2014-08-22 Manuel López-Ibáñez <manu@gcc.gnu.org> * c.opt (Wcomment): Use CPP, Var and LangEnabledBy. (Wmultichar): Likewise. (Wdate-time): Use C-family languages instead of Common. Use CPP and Var. * c-opts.c (c_common_handle_option): Do not handle the above options here. (sanitize_cpp_opts): Likewise. gcc/testsuite/ChangeLog: 2014-08-22 Manuel López-Ibáñez <manu@gcc.gnu.org> * g++.dg/warn/wdate-time.C: Remove. * gcc.dg/wdate-time.c: Move from here... * c-c++-common/wdate-time.c: ... to here.
