        * lang.opt (Wconversion-extra): New option.
        * gfortran.h (gfc_option_t): Add warn_conversion_extra.
        * options.c (gfc_init_options): Disable -Wconversion-extra by default.
        (set_Wall): Enable -Wconversion.
        (gfc_handle_option): Set warn_conversion_extra.
        * intrinsic.c (gfc_convert_type_warn): Ignore kind conditions
        introduced for -Wconversion if -Wconversion-extra is present.
        * invoke.texi: Add -Wconversion to -Wall; document new behaviour of
        -Wconversion; document -Wconversion-extra.
