Subject: build: use _GL_ATTRIBUTE_NONSTRING attribute to avoid new warnings
X-Git-Tag: v9.7~4
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=42f6201aa554fde4c78a3c5d0207d85392eb742e;p=thirdparty%2Fcoreutils.git

build: use _GL_ATTRIBUTE_NONSTRING attribute to avoid new warnings

Avoid warnings like this from GCC 15:
src/basenc.c:1139:20: error: initializer-string for array of 'char'
truncates NUL terminator but destination lacks 'nonstring' attribute
(9 chars into 8 available) [-Werror=unterminated-string-initialization]
* src/basenc.c (z85_encoding, do_decode): Mark two more variables as
non-terminated.
