Hi

(Darwin tests both GNU and NeXT runtimes).

The version 2 GNU Objective C API is mostly compatible with the NeXT one.
However, there are a few testsuite tweaks needed (and one test fails for NeXT
without considerable increase in complexity).

tested across the Darwin range, and on x86_64-linux
pushed to master
thanks
Iain

gcc/testsuite/ChangeLog:

	* obj-c++.dg/gnu-api-2-class-meta.mm: Add a flag to cause NeXT
	headers to expose prototypes for messaging.
	* obj-c++.dg/gnu-api-2-class.mm: Likewise.
	* obj-c++.dg/gnu-api-2-objc.mm: Skip this because of the extra
	protocols pulled in by system headers.
