Update.
1998-02-25 08:28 H.J. Lu <hjl@gnu.org>
* math/test-fenv.c (print_rounding): Fix a typo in
FE_TOWARDSZERO.
* sysdeps/alpha/fpu/fraiseexcpt.c (feraiseexcept): Use a dummy
for FE_DIVBYZERO. Kludge for FE_UNDERFLOW.
1998-02-26 14:59 Ulrich Drepper <drepper@cygnus.com>
* stdio-common/vfscanf.c [!USE_IN_LIBIO] (inchar): Add missing braces.
1998-02-19 11:00 Zack Weinberg <zack@rabi.phys.columbia.edu>
* Makefile.in: Disable built-in rules.
1998-02-21 Andreas Jaeger <aj@arthur.rhein-neckar.de>
* sysdeps/i386/fpu/t_exp.c: Move to ...
* sysdeps/libm-i387/t_exp.c: ... here.
1998-02-21 13:51 H.J. Lu <hjl@gnu.org>
* sysdeps/libm-ieee754/s_exp2f.c (__exp2f_deltatable): Renamed
from __exp2_deltatable.
