Ian, Thanks for your reference link! I also went through gcc manual several days ago to learn the correct usage of __attribute__((deprecated)). While there are also cases where it is misused. That's the point I concerned here. For the first case in 2, following texts in your link might explain why the compiling failed: "An attribute specifier list may, in future, be permitted to appear after the declarator in a function definition (before any old-style parameter declarations or the function body)." I am looking forward to this change in the future. While for the case in 3, it's better for gcc to give a warning if it cannot take effect.
