+	[BZ #17748]
+	* include/fenv.h (__fegetround): Declare.  Use libm_hidden_proto.
+	* math/fegetround.c (fegetround): Rename to __fegetround and
+	define as weak alias of __fegetround.  Use libm_hidden_weak.
+	* sysdeps/aarch64/fpu/fegetround.c (fegetround): Likewise.

+	(__fegetround): Also undefine macro after function definition.
+	* sysdeps/powerpc/nofpu/fegetround.c (fegetround): Rename to
+	__fegetround and define as weak alias of __fegetround.  Use
