[BZ #2423]
2006-03-07  Jakub Jelinek  <jakub@redhat.com>
	[BZ #2423]
	* math/libm-test.inc [TEST_LDOUBLE] (ceil_test, floor_test, rint_test,
	round_test, trunc_test): Only run some of the new tests if
	LDBL_MANT_DIG > 100.

	    Alan Modra  <amodra@bigpond.net.au>

	* sysdeps/powerpc/fpu/fenv_libc.h (__fegetround, __fesetround):
	Define inline implementations.
	* sysdeps/powerpc/fpu/fegetround.c: Use __fegetround.
	* sysdeps/powerpc/fpu/fesetround.c: Use __fesetround.

	* sysdeps/powerpc/fpu/math_ldbl.h: New file.

	[BZ #2423]
