<sys/cdefs.h>: Add __min_size(x) macro

C99 allows to use the 'static' keyword in function array parameter
declarators, which helps the compiler better validate the passed
argument and optimize code.  However, this syntax isn't allowed in C++.

This macro allows us both to use this C99 feature and to use the headers
in C++.
