Browse source 
Under a configuration including `cppflags=-DUNIVERSAL_PARSER`, warnings listed below show in build time:

```
node.c:396:30: warning: initialization left-hand side might be a candidate for a format attribute [-Wsuggest-attribute=format]
  396 |     bug_report_func rb_bug = ast->node_buffer->config->bug;
      |                              ^~~
```

```
ruby_parser.c:655:21: warning: initialization left-hand side might be a candidate for a format attribute [-Wsuggest-attribute=format]
  655 |     .compile_warn = rb_compile_warn,
      |                     ^~~~~~~~~~~~~~~
ruby_parser.c:656:24: warning: initialization left-hand side might be a candidate for a format attribute [-Wsuggest-attribute=format]
  656 |     .compile_warning = rb_compile_warning,
      |                        ^~~~~~~~~~~~~~~~~~
ruby_parser.c:657:12: warning: initialization left-hand side might be a candidate for a format attribute [-Wsuggest-attribute=format]
  657 |     .bug = rb_bug,
      |            ^~~~~~
ruby_parser.c:658:14: warning: initialization left-hand side might be a candidate for a format attribute [-Wsuggest-attribute=format]
  658 |     .fatal = rb_fatal,
      |              ^~~~~~~~
```

To fix, this patch suggests adding `__attribute__((format(printf, n, m)))` to those function declarations.
