Update.
2002-07-03 Jakub Jelinek <jakub@redhat.com>
* stdio-common/printf_fp.c (__printf_fp.c): If _FPIO_CONST_SHIFT is
non-zero, adjust exponent.
* sysdeps/ieee754/ldbl-128/s_erfl.c (__erfl, erfl, __erfcl, erfcl):
Remove NO_LONG_DOUBLE aliases.
* sysdeps/ieee754/ldbl-128/s_expm1l.c (__expm1l, expm1l): Likewise.
* sysdeps/ieee754/ldbl-128/s_log1pl.c (__log1pl, log1pl): Likewise.
(__log1pl): Raise divide by zero and invalid exceptions when needed.
* sysdeps/ieee754/ldbl-128/e_powl.c (__ieee754_powl): Special case
1**y and -1**+-Inf.
* sysdeps/ieee754/ldbl-128/ldbl2mpn.c (__mpn_extract_long_double):
Fix BITS_PER_MP_LIMB 32 extraction.

* sysdeps/ieee754/ldbl-128/e_lgammal_r.c (__ieee754_lgamma_r):
Raise exceptions when needed. Don't recurse unnecessarily.
Special case 1.0L and 2.0L arguments to avoid -0.0L as result.
* sysdeps/ieee754/ldbl-128/e_j0l.c (__ieee754_y0l): Don't raise
exceptions for qNaNs.
* sysdeps/ieee754/ldbl-128/s_remquol.c (__remquol): Make qs 64-bit
to fix *quo return value sign.
