Do you have any other ideas how can you display this information to the
users/customers, that it is time to stop using the uppercase header files then
they shall to use its merged lowercase named files instead in their userspace
SW?
``__attribute__`` is just as implementation-specific as ``#pragma``, so it's
not really an improvement, but here goes:
----
struct __attribute__((deprecated("This header file is deprecated"))) dontusethisstruct {
};
extern struct dontusethisstruct undefinedstruct;
----
As i know it is a feature only in GCC, can it work with Clang compiler?

By the way it is perfect for through a warning for a deprecated struct, function
etc ... only in GCC, but it is not ideal to use a simple header file include and
the syntax of it is horryble. Usage of a generic #pragma message is more
feasible in all compilers.
