1997-06-26 21:50 Ulrich Drepper <drepper@cygnus.com> * math/math.h: Move definition of macros for unordered comparison after inclusion of <bits/mathinline.h>. * sysdeps/i386/fpu/bits/mathinline.h: Don't undef macros for unordered comparison before definition. * sysdeps/m68k/fpu/bits/mathinline.h: Likewise. * Makerules: Move definition of load-map-file before use. (lib%.so): Depend on load-map-file, not lib%-map. * manual/lgpl.texinfo: Likewise. 1997-06-24 09:40 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * sysdeps/m68k/fpu/bits/mathinline.h: Don't define __ilogb. * sysdeps/m68k/fpu/s_ilogb.c: Define it here. Handle zero, NaN and infinity specially. * sysdeps/m68k/fpu/s_ilogbf.c, sysdeps/m68k/fpu/s_ilogbl.c: Adapted. * sysdeps/m68k/fpu/bits/mathdef.h (FP_ILOGB0): Correct value. 1997-06-26 17:06 Ulrich Drepper <drepper@cygnus.com> * configure.in: Don't use .long in tests since some strange platforms without binutils don't know this. Redirect output of test commands correctly. Patch by Klaus Espenlaub <kespenla@hydra.informatik.uni-ulm.de>. * hurd/hurdsig.c (_hurdsig_init): Call _hurd_self_sigstate. Patch by Kazumoto Kojima <kkojima@kk.info.kanagawa-u.ac.jp>. 1997-06-26 09:02 Fila Kolodny <fila@ibi.com> * sysdeps/mach/hurd/abi-tag.h: New file. * sysdeps/mach/bits/libc-lock.h: Add typedef for __libc_key_t. * sysdeps/stub/bits/libc-lock.h: Likewise. * sysdeps/mach/hurd/accept.c (accept): Fix type of parameter addrarg. Add variable addr containing the desired part of the union. * sysdeps/mach/hurd/recvfrom.c (recvfrom): Likewise. * sysdeps/mach/hurd/getsockname.c (getsockname): Likewise. * sysdeps/mach/hurd/getpeername.c (getpeername): Likewise. * sysdeps/mach/hurd/connect.c (__connect): Likewise. * sysdeps/mach/hurd/bind.c (bind): Likewise. * sysdeps/mach/hurd/select.c (__select): Change MACH_MSG_SIZE_INTEGER_T to sizeof(MACH_MSG_TYPE_INTEGER_T). * io/ftw.c (ftw_startup): Use PATH_MAX only if defined. * sysdeps/mach/hurd/open.c (__open): Fix type of parameter file. * sysdeps/mach/hurd/sysd-stdio.c (__stdio_reopen): Add closefn to paramater list since it is used. * sysdeps/mach/hurd/rename.c (rename): Fix type of paramater new. * sysdeps/mach/hurd/sigaltstack.c (sigaltstack): Change parameter from ss to argss. 1997-06-24 14:02 Andreas Jaeger <aj@arthur.rhein-neckar.de> * Rules: Update copyright. * mach/Machrules: Likewise. 1997-06-26 14:28 Ulrich Drepper <drepper@cygnus.com> * configure.in: Fix accidently removed AC_OUTPUT line. Reported by Andreas Jaeger. * time/strftime.c: Don't define `memcpy' macro if HAVE_MEMCPY is defined. Reported by Akim Demaille <demaille@inf.enst.fr>. * sysdeps/generic/getdomain.c: Include handling for stub case. This eliminated the only case of a function in generic and stub. * sysdeps/stub/getdomain.c: Removed. Patch by Zack Weinberg <zack@rabi.phys.columbia.edu>. 1997-06-23 22:20 Andreas Jaeger <aj@arthur.rhein-neckar.de> * sysdeps/alpha/_mcount.S: Update and reformat copyright, remove trailing white spaces
