This allows to reduce the number of public interfaces. * src/getargs.c (--yacc): Use warning_argmatch instead of tweaking directly warnings_flag (which will be private). (warning_argmatch, warnings_argmatch): Move to... * src/complain.h, src/complain.c: here. * src/getargs.h, src/getargs.c (warnings_args, warnings_types): Move to... * src/complain.c: here, now private. * src/complain.h (severity, warnings_flag): Move to... * src/complain.c: here, now private.
