Patch by Thorsten Kukuk.
1998-02-26 Thorsten Kukuk <kukuk@vt.uni-paderborn.de>
* nis/ypclnt.c: Give clnt handle after error checking free, change
return codes to fix problems with rpc.nisd in YP mode on Ultra's.

* misc/fstab.c: Partly rewritten to use dynamically allocated buffer.
Patch by Joe Keane <jgk@jgk.org>.
* misc/fstab.h (struct fstab): Change fs_type member to be const.
* misc/fstab.c: Remove casts in fs_type assignments.
1998-02-26 Andreas Jaeger <aj@arthur.rhein-neckar.de>
* sysdeps/i386/fpu/bits/fenv.h: Correct typo. ISO C 9X defines
FE_TOWARDZERO and not FE_TOWARDSZERO. Reported by H.J. Lu.
* sysdeps/sparc/sparc64/fpu/bits/fenv.h: Likewise.
* sysdeps/sparc/sparc32/fpu/bits/fenv.h: Likewise.
* sysdeps/powerpc/bits/fenv.h: Likewise.
* sysdeps/m68k/fpu/bits/fenv.h: Likewise.
* sysdeps/generic/bits/fenv.h: Likewise.
* sysdeps/alpha/fpu/bits/fenv.h: Likewise.
* sysdeps/i386/fpu/fesetenv.c (fesetenv): Likewise.
* sysdeps/powerpc/test-arith.c (main): Likewise.
1998-02-25 Ulrich Drepper <drepper@cygnus.com>
* sysdeps/i386/fpu/bits/mathinline.h: Also fix i386 versions of
the comparison macros.
1998-02-21 20:14 H.J. Lu <hjl@gnu.org>
* sysdeps/libm-ieee754/s_log2.c (ln2): Added.
(__log2): Fixed return values.
* sysdeps/libm-ieee754/s_log2f.c: Likewise.
1998-02-25 Ulrich Drepper <drepper@cygnus.com>
* math/math.h (isunordered): Rename local variables to ensure
correct code. Reported by HJ Lu.
1998-02-25 10:34 Ulrich Drepper <drepper@cygnus.com>
* sysdpes/i386/fpu/bits/mathinline.h (isgreater, isgreaterequal,
isless, islessequal, islessgreater, isunordered): Fix syntax for
fucompip instruction.
(isless, islessequal): Fix logic.
1998-02-21 Andreas Jaeger <aj@arthur.rhein-neckar.de>
* math/libm-test.c (sqrt_test): Add test for sqrt(2).
(comparisons_test): New tests for comparison macros.
