==================== Branch work171-bugs, patch #301 ====================
+Do not build IEEE 128-bit libgcc support if VSX is not available.
+
+In the past, we would build libgcc and eable the float128 libraries by adding
+-mvsx -mabi=altivec to build the support libraries. However, this causes
+problems if the default cpu is a 7450.
+
+With this fix, in order to build the float128 support, the compiler must be
+configured to default to at least power7 to enable using the VSX register set,
+which is required for passing float128 values.
+
+If somebody wanted to enable float128 on big endian systems, they would need to
+use a compiler that defaults to at least power7.
