gcc/errors.cc lacks ATTRIBUTE_PRINTF_1 for the definition of `warning`,
`error`, `fatal`, and `internal_error`, which generate following
warnings when compiling GCC:
../../gcc-16.1.0/gcc/errors.cc: In function 'void warning(const char*, ...)':
../../gcc-16.1.0/gcc/errors.cc:51:12: warning: function 'void warning(const
char*, ...)' might be a candidate for 'gnu_printf' format attribute
[-Wsuggest-attribute=format]
51 | vfprintf (stderr, format, ap);
| ~~~~~~~~~^~~~~~~~~~~~~~~~~~~~
<Likewise for error, fatal, and internal_error>
gcc/ChangeLog:
PR driver/126500
* errors.cc: Add missing ATTRIBUTE_PRINTF_1 for the definition
of `warning`, `error`, `fatal`, and `internal_error`.
