Subject: maint: prefer endian.h macros to WORDS_BIGENDIAN
X-Git-Tag: v9.8~249
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=991934d9c9ea55be4e3298278782d4a377ee7d8f;p=thirdparty%2Fcoreutils.git

maint: prefer endian.h macros to WORDS_BIGENDIAN

* src/od.c: Include endian.h.
(WORDS_BIGENDIAN): Remove definition.
(main): Use BYTE_ORDER, BIG_ENDIAN, LITTLE_ENDIAN instead of
WORDS_BIGENDIAN. Fix formatting.
