+==================== work093, patch #2
+
+Add support to built-ins for long double using IEEE 128-bit.
+
+This patch lays the ground work that future patches will use to add
+builtin support (both normal and overloaded) for the case where long
+double uses the IEEE 128-bit encoding.  The issue to enable migrating the
+builtins to use the overload facility to allow both __float128 and long
+double to the functions.
+
+This adds a new stanza (ieee128-hw-ld) for when we have IEEE 128-bit
+hardware support and long double uses the IEEE 128-bit encoding.
+
+A new type attribute (ieeeld) is added for long double if long double uses
+the IEEE 128-bit encoding.
