GCC 4.6 objc-api.h said:
/* This file declares the "traditional" GNU Objective-C Runtime API.
It is the API supported by older versions of the GNU Objective-C
Runtime. Include this file to use it.
This API is being replaced by the "modern" GNU Objective-C Runtime
API, which is declared in objc/runtime.h. The "modern" API is very
similar to the API used by the modern Apple/NeXT runtime.
The last version of GCC supporting the traditional API is GCC 4.6.
This file will not exist in later versions of GCC.
Because the two APIs have some conflicting definitions (in
particular, Method and Category are defined differently) you should
include either objc/objc-api.h (to use the traditional GNU
Objective-C Runtime API) or objc/runtime.h (to use the modern GNU
Objective-C Runtime API), but not both. */
so it is surprising that gnustep maintainers didn't bother to do anything
to move toward objc/runtime.h. And it surprises me that clang actually
didn't remove that header too, I'd have thought that Nicola Pero
removed it because it was gone in clang/llvm too.
