Update.
1998-02-26 Ulrich Drepper <drepper@cygnus.com>
* nis/ypclnt.c (yp_master): Check result of strdup.
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.
1998-02-26 09:00 Ulrich Drepper <drepper@cygnus.com>
* 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>

(__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>
