-Wwrite-strings: Constify macroexp.c:init_shared_buffer
There's one call in the file that passes a string literal, like: init_shared_buffer (&va_arg_name, "__VA_ARGS__", strlen ("__VA_ARGS__")); Instead of adding a cast here, make init_shared_buffer take a 'const char *', and remove the several casts in the file that are made obsolete. gdb/ChangeLog: 2017-04-05 Pedro Alves <palves@redhat.com> * macroexp.c (macro_buffer::shared): Now a bool. (init_buffer): Update. (init_shared_buffer): Constify 'addr' parameter. (substitute_args, expand, macro_expand, macro_expand_next): Remove casts.
