Subject: [BZ #22593] Fix nextafter and nexttoward declaration
X-Git-Tag: glibc-2.27~296
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=4e0dca54e945716a59f4e0b6b1f16415b3d4ed8e;p=thirdparty%2Fglibc.git

[BZ #22593] Fix nextafter and nexttoward declaration

These functions set errno and thus the const attribute was wrong.

	[BZ #22593]
	* math/bits/mathcalls.h (nextafter): Remove const.
	(nexttoward): Likewise.
