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.
