Subject: e2fsck: Portability fix: Use WORDS_BIGENDIAN instead of __LITTLE_ENDIAN
X-Git-Tag: v1.41.1~60
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=094c2d43939533113ededfd6fe49ad1c7726df29;p=thirdparty%2Fe2fsprogs.git

e2fsck: Portability fix: Use WORDS_BIGENDIAN instead of __LITTLE_ENDIAN

__LITTLE_ENDIAN is set by the glibc headers, and isn't portable.  We
should be using WORDS_BIGENDIAN, which is set by autoconf.
