RE: Regarding compiling - __attribute__((deprecated))

[LiLy <xmlymt at hotmail dot com>]

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.


Best Regards,
Ly
