Subject: Don't include inttypes.h or stdint.h.
X-Git-Tag: v5.3.0~983
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=5682fe455f57678dbc678fc45188d7435383db73;p=thirdparty%2Fcoreutils.git

Don't include inttypes.h or stdint.h.
(UNALIGNED_P): Remove.
(__memrchr): Use size_t, not uintptr_t, to test alignment.
