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.
