The testcases work correctly on AIX and powerpc64-linux, so this likely is due
to Darwin not implementing consistent aggregate padding rules in GCC for
backward compatibility.

Increasing the value of MOVE_RATIO and CLEAR_RATIO decreases SPEC

libstdc++ is calling frexpl in libc.a, which expects an AIX format long double

Is this compiled with -mlong-double-128 or using the default, which is
-mlong-double-64 on AIX? GCC currently does not build a long-double-128
multilib on AIX, which would be necessary for that mode to work
