+	* include/features.h (__GLIBC_HAVE_LONG_LONG): Remove.
+	* bits/byteswap.h [__GLIBC_HAVE_LONG_LONG]: Change #elif condition

+	[__GLIBC_HAVE_LONG_LONG && __USE_BSD]: Change to [__USE_BSD].
+	* string/byteswap.h [__GLIBC_HAVE_LONG_LONG]: Make code
+	unconditional.
+	* string/endian.h [__GLIBC_HAVE_LONG_LONG]: Likewise.
