Subject: Fix endianness detection in memcopy.h
X-Git-Tag: 1.9.9-b1~497
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=cde1daff92c8a31b5c6cbd5362181f29f153e375;p=thirdparty%2Fzlib-ng.git

Fix endianness detection in memcopy.h

When memcopy.h is included into inffast.c, endianness-related
preperocessor defines are not set, which leads to
BYTE_ORDER == LITTLE_ENDIAN condition being always true. This breaks
decompression at least on s390x.
