+Subject: [PATCH 2/4] Remove broken ieeefp.h macros
+
+Any attempt to use isnanf, isinff, or finitef from <ieeefp.h> with
+GCC 5 on platforms other than SPU result in a "lvalue required as
+unary '&' operand" error.
+
+	newlib/libc/
+	* include/ieeefp.h (__ieeefp_isnanf): Remove broken macro.
+	(__ieeefp_isinff, __ieeefp_finitef): Ditto.
