Subject: [PATCH] LWG 2441 Provide exact-width atomic typedefs
Authentication-results: sourceware.org; auth=none

	* include/std/atomic (atomic_int8_t, atomic_uint8_t, atomic_int16_t)
	(atomic_uint16_t, atomic_int32_t, atomic_uint32_t, atomic_int64_t)
	(atomic_uint64_t): Define (LWG 2441).
	* testsuite/29_atomics/headers/atomic/std_c++0x_neg.cc: Remove empty
	lines.
	* testsuite/29_atomics/headers/atomic/types_std_c++0x.cc: Test for
	the new types.
	* doc/xml/manual/intro.xml: Document DR 2441 status.

I've chosen to treat this as a DR and defined the types even for
-std=c++11 and -std=c++14. Again, if there are strong objections that
could be changed to only define them for -std=c++17 or -std=gnu++NN
but I'd rather not do that.

Tested x864-linux, committed to trunk
.
