	This has been discussed on the GCC mailinglist before.  Because
Gnat cannot link with the GCC infrastructure defining this variable to
provide variable size, it needs to assume 64-bit long double for now.

I found

	http://gcc.gnu.org/ml/gcc/2002-03/msg00809.html

but this was before branching for 3.1/3.2.

ok, found. should this be applied to the 3.3 branch again?

	Maybe.  Or maybe it should be defined identically to
LIBGCC2_LONG_DOUBLE_TYPE_SIZE so if it ever is compiled with
long-double-128 it gets the appropriate target size.  I see that sol2.h
defines it, but the discussion for PowerPC was inconclusive.
