Subject: lib/attr.h: Use C23-style attributes
X-Git-Tag: 4.17.0-rc1~171
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=060b0849a6433a17685cf73b1816603b00657f95;p=thirdparty%2Fshadow.git

lib/attr.h: Use C23-style attributes

They're stricter.  The GNU attributes are too lazy, and can be misused
more easily.  Also, mixing both has its own problems.
