commit b1aa60f32d34030b28bca04aeee084cd3bedecfa
Author: Andreas Jaeger <aj@suse.de>
Date: Wed Mar 28 16:39:25 2012 +0200
Add __bswap_64 definition for non GCC compilers.
[BZ#13926]
Currently __bswap_64 is not defined at all for non-GCC compilers.
Define it but guard it with __GLIBC_HAVE_LONG_LONG.
endian.h uses __bswap_64, make the functions only available
if __GLIBC_HAVE_LONG_LONG is defined.
