+If you are on a PowerPC system where the default long double is IEEE
+128-bit, GCC will use the wrong names for some of the conversion functions
+for the __ibm128 type.
+
+What is happening is when the defult long double is IEEE 128-bit, the
+various convert, truncation, and extend functions did not specify a
+default name for the conversion.  The machine indepentent portions of the
+compiler would construct a call with an 'if' name (IFmode being the mode
