Update.

1998-12-28  Ulrich Drepper  <drepper@cygnus.com>

	* stdlib/fpioconst.c: If __NO_LONG_DOUBLE_MATH don't define constants
	beyond range of double.
	* stdlib/fpioconst.h (_fpioconst_pow10): Reduce size according to
	fpioconst.c change.
	* stdlib/strtold.c: Fall back on double functions if
	__NO_LONG_DOUBLE_MATH.
	* stdlib/strtold_l.c: Likewise.
	* wcsmbs/wcstold.c: Likewise.
	* wcsmbs/wcstold_l.c: Likewise.
	* sysdeps/ieee754/ldbl2mpn.c: Don't generate code if
	__NO_LONG_DOUBLE_MATH.
	* sysdeps/ieee754/mpn2ldbl.c: Likewise.

1998-12-28  Geoff Keating  <geoffk@ozemail.com.au>

	* sysdeps/powerpc/bits/endian.h: Use #warning, not #error, if
	the endianness can't be determined, for makedepend.
