The AC_C_ATTRIBUTE_ALIGNED macro is broken, it always reports maximum aligned available as 64 even on Darwin where the maximum is 16, as it does not use -Werror, and the wrong alignment is considered only a warning. Rewrite it as CC_ATTRIBUTE_ALIGNED (in attributes.m4, where other similar macros are located). Also reverse the order of the checks, so that the highest version is tried first; this way you can avoid five compile tests on systems where 64 is the highest alignment available.
