Update.
1998-11-30 Andreas Jaeger <aj@arthur.rhein-neckar.de> * nscd/nscd_getpw_r.c: Include nscd_proto.h for prototypes. * sysdeps/generic/errno-loc.c: Include <errno.h> for prototype, undefine errno to get variable. * sysdeps/unix/sysv/linux/i386/setfsuid.c: Include <sys/fsuid.h> instead of <unistd.h> for prototype. * sysdeps/unix/sysv/linux/i386/setfsgid.c: Likewise. 1998-11-30 Ulrich Drepper <drepper@cygnus.com> * misc/err.h: Correct comments and use protected attribute keywords. Reported by Joseph Myers <jsm28@cam.ac.uk>. 1998-11-29 Roland McGrath <roland@baalperazim.frob.com> * malloc/thread-m.h [_LIBC]: Include <bits/libc-tsd.h>, and remove tsd stuff from pthreads/cthreads libc sections. Use __libc_tsd_define for MALLOC key. [_LIBC] (tsd_key_t, tsd_key_create): Define to a zero-size type and a no-op, respectively. [_LIBC] (tsd_setspecific, tsd_getspecific): Use __libc_tsd_get/set. * elf/dl-error.c: Include <bits/libc-tsd.h>. Use __libc_tsd_define for DL_ERROR key. (tsd_setspecific, tsd_getspecific): Rewritten using __libc_tsd_get/set. * sysdeps/mach/hurd/bits/libc-tsd.h: New file. * sysdeps/generic/bits/libc-tsd.h: New file. * Makefile (distribute): Add bits/libc-tsd.h. 1998-10-12 Roland McGrath <roland@baalperazim.frob.com> * elf/dl-error.c: Remove kludge to check for ld.so load address. There is no need if weak undefined symbols are not used in ld.so; see linuxthreads/ChangeLog for changes to files linuxthreads/sysdeps/pthread/bits/libc-lock.h and linuxthreads/sysdeps/pthread/bits/libc-tsd.h. 1998-11-30 Andreas Jaeger <aj@arthur.rhein-neckar.de> * sysdeps/i386/bits/string.h (__memset_cc): Fix typo (s->__s). * sysdeps/i386/i486/bits/string.h: Add prototypes for all new inline functions. * sysdeps/i386/bits/string.h: Likewise. 1998-11-30 Andreas Jaeger <aj@arthur.rhein-neckar.de> * sysdeps/unix/sysv/linux/alpha/bits/ipc.h: Remove ipc_kludge. 1998-11-30 Andreas Schwab <schwab@issan.cs.uni-dortmund.de> * db2/progs/db_load/db_load.c (main): Avoid -Wparentheses warning.

calls can come from `_dl_map_object_deps', `_dlerror_run', or from
any of the libc functionality which loads dynamic objects (NSS, iconv).
Therefore we have to be prepared to save the state in thread-local
- memory. `catch' will only be used for the non-threaded case.

- Please note the horrible kludge we have to use to check for the
- thread functions to be defined. The problem is that while running
- ld.so standalone (i.e., before the relocation with the available
- libc symbols) we do not have a real handling of undefined weak symbols.
- All symbols are relocated, regardless of the availability. They are
- relocated relative to the load address of the dynamic linker. Adding
- this start address to zero (the value in the GOT for undefined symbols)
- leads to an address which is the load address of ld.so. Once we have
- relocated with the libc values the value is NULL if the function is
- not available. Our "solution" is to regard NULL and the ld.so load
- address as indicators for unavailable weak symbols. */
