Update.
1998-07-31 17:59 Ulrich Drepper <drepper@cygnus.com> * sysdeps/generic/bits/byteswap.h: Fix problems with side effects. * manual/filesys.texi: Document truncate and ftruncate. Patch by Michael Deutschmann <michael@talamasca.wkpowerlink.com>. * shadow/putspent.c: Lock stream while generating the output. * sunrpc/clnt_unix.c: Use ucred instead of cmsgcred again. (__msgwrite): Rewrite accordingly. * sunrpc/svc_unix.c: Likewise. * sysdeps/unix/sysv/linux/Dist: Remove __recvmsg.S and __sendmsg.S. * sysdeps/unix/sysv/linux/Makefile [$(subdir)==socket] (sysdep_routines): Remove __sendmsg and __recvmsg. * sysdeps/unix/sysv/linux/__recvmsg.S: Removed. * sysdeps/unix/sysv/linux/__sendmsg.S: Removed. * sysdeps/unix/sysv/linux/recvmsg.c: Removed. * sysdeps/unix/sysv/linux/sendmsg.c: Removed. * sysdeps/unix/sysv/linux/recvmsg.S: New file. * sysdeps/unix/sysv/linux/sendmsg.S: New file. * sysdeps/unix/sysv/linux/bits/socket.h: Define SCM_CREDENTIALS and struct ucred. Remove struct cmsgcred. Patches by Thorsten Kukuk. 1998-08-03 Andreas Jaeger <aj@arthur.rhein-neckar.de> * inet/rcmd.c (__ivaliduser): Allow '#' as comment character. 1998-08-08 14:42 Ulrich Drepper <drepper@cygnus.com> * argp/argp-help.c: Prepare to be used outside glibc without gcc by adding usual alloca cruft. Reported by Eleftherios Gkioulekas <lf@amath.washington.edu>. 1998-04-05 Jim Meyering <meyering@ascend.com> * lib/regex.c (WIDE_CHAR_SUPPORT): Define. This now depends on HAVE_BTOWC so systems that lack btowc (like solaris-2.5.1) don't lose. 1998-08-07 Mark Kettenis <kettenis@phys.uva.nl> * sysdeps/generic/bits/sigaction.h: Remove definition of SA_DISABLE. * sysdeps/generic/bits/sigstack.h: Define SS_DISABLE, SS_ONSTACK, MINSIGSTKZ and SIGSTKSZ. Definitions match BSD. * hurd/sigunwind.c (_hurdsig_longjmp_from_handler): Use SS_ONSTACK instead of SA_ONSTACK. * sysdeps/mach/hurd/sigaltstack.c (__sigaltstack): Renamed from sigaltstack, and created a weak alias. Use SS_DISABLE and SS_ONSTACK instead of SA_DISABLE and SA_ONSTACK. * sysdeps/mach/hurd/sigstack.c (sigstack): Use SS_ONSTACK instead of SA_ONSTACK. Call __sigaltstack instead of sigaltstack. * sysdeps/mach/hurd/i386/sigreturn.c (__sigreturn): Use SS_ONSTACK instead of SA_ONSTACK. * sysdeps/mach/hurd/alpha/sigreturn.c (__sigreturn): Likewise. * sysdeps/mach/hurd/mips/sigreturn.c (__sigreturn): Likewise. * sysdeps/mach/hurd/i386/trampoline.c (_hurd_setup_sighandler): Use SS_DISABLE instead of SA_DISABLE.

(shared-only-routines): Likewise. * libio/oldtmpfile.c: New file * stdio-common/tmpfile.c: Use __fdopen and __close. [USE_IN_LIBIO]: Use _IO_fdopen instead of _IO_new_fdopen. Put tmpfile on symbol version GLIBC_2.1. * stdio-common/tmpfile64.c: Use __fdopen and __close.

[USE_IN_LIBIO]: Map __fdopen to _IO_fdopen. * sysdeps/posix/tempname.c (__gen_tempname): Don't bother checking __stub_open64, it is never defined. 1998-08-05 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * libio/iofopen64.c: Fix typo. Avoid unnessary casts. * libio/iopopen.c: Unlink file before freeing it if command creation failed. Avoid unnessary casts. * libio/iofdopen.c: Avoid unnecessary cast. * pwd/fgetpwent_r.c [USE_IN_LIBIO]: Map funlockfile to _IO_funlockfile. * pwd/fgetspent_r.c [USE_IN_LIBIO]: Likewise. 1998-08-06 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * grp/grp.h, pwd/pwd.h: Don't declare __grpopen, __grpread, __grpalloc, __grpscan and the corresponding pwd functions, they were removed long ago. 1998-08-06 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * math/libm-test.c (csqrt_test): Adjust epsilons.
