From aabe2441765c632bba697945491e3e0ac29ac886 Mon Sep 17 00:00:00 2001 From: Fabian Groffen Date: Sat, 8 Jan 2011 19:49:38 +0100 Subject: build-sys: use WORDS_BIGENDIAN to determine platform byte-order Autoconf contains the right magic to determine the endianness on many platforms next to Linux. This reverses previous commits to move away from WORDS_BIGENDIAN: "use __BYTE_ORDER rather than AC specific WORDS_BIGENDIAN" This is necessary to compile on non Linux platforms like Darwin and Solaris.
