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> * 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.
