1997-06-27 20:09 Ulrich Drepper <drepper@cygnus.com> * sysdeps/unix/sysv/linux/sys/quota.h: Add <asm/types.h>. Reported by a sun <asun@zoology.washington.edu>. * libc.map: Add _rpc_dtablesize. Reported by Thorsten Kukuk. * db/makedb.c: Exit with error if number of option is incorrect. * math/Makefile (tests): Add test-fenv. * math/test-fenv.c: New file. Test for exception handling functions. Written mainly by Andreas Jaeger. * sysdeps/i386/fpu/fraiseexcpt.c: Correct implementation. * sysdeps/mach/hurd/abi-tag.h: Set tag to 1 for Hurd and kernel compatibility version to 0. Reported by Roland McGrath. 1997-06-27 18:49 Philip Blundell <Philip.Blundell@pobox.com> * sysdeps/standalone/brk.c (__NONE_set_memvals): Correct typo. * sysdeps/standalone/arm/bits/errno.h: Add ENOTDIR. * sysdeps/stub/sys/param.h: Add definition of MAX and MIN. 1997-06-27 10:44 Fila Kolodny <fila@ibi.com> * sysdeps/mach/hurd/dl-sysdep.c: Make _dl_sysdep_read_whole_file weak. 1997-06-27 00:51 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * elf/dl-open.c (_dl_open): Check versions of all newly loaded objects, including dependencies. * elf/dl-runtime.c (fixup): Always use version information if available. 1997-06-26 12:25 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * sysdeps/m68k/bits/nan.h: Renamed from sysdeps/m68k/nan.h. 1997-06-26 11:40 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * posix/regex.c (DEBUG_POP): Assume parameter to be pointer to int, not pointer to fail_stack_elt_t. (PUSH_FAILURE_POINT): Fix all formats in debugging messages. Fix type of this_reg. (POP_FAILURE_POINT): Likewise. Fix type of failure_id. (re_match_2_internal): Pass NULL, not 0, to PUSH_FAILURE_POINT. 1997-06-27 02:17 Ulrich Drepper <drepper@cygnus.com> * sysdeps/unix/sysv/linux/syscalls.list: Add quotactl. Reported by a sun. * manual/lgpl.texinfo: Update copyright.
