Update.

1999-05-11 Ulrich Drepper <drepper@cygnus.com> * elf/Versions (ld.so) [GLIBC_2.1.1]: Add _dl_lazy. * elf/dl-open.c (_dl_open_worker): Only relocate newly loaded objects lazily if LD_BIND_NOW is not set. * elf/dl-support.c (_dl_lazy): New variable. (non_dynamic_init): Set _dl_lazy according to LD_BIND_NOW envvar. * elf/rtld.c (_dl_lazy): new global variable. ( dl_main): Remove lazy, replace it by _dl_lazy. 1999-05-06 Andreas Schwab <schwab@issan.cs.uni-dortmund.de> * locale/setlocale.c (new_composite_name): Check also whether the first category name differs. 1999-05-11 Andreas Schwab <schwab@issan.cs.uni-dortmund.de> * sysdeps/unix/sysv/linux/ftime.c: Use the bsd implementation, not the generic one. 1999-05-11 Philip Blundell <pb@nexus.co.uk> * sysdeps/generic/bits/socket.h (struct sockaddr_storage): New structure; storage suitable for any socket address. * sysdeps/unix/sysv/linux/bits/socket.h (struct sockaddr_storage): Likewise. * sysdeps/unix/sysv/linux/mips/bits/socket.h (struct sockaddr_storage): Likewise. * inet/netinet/in.h: Use ULONG_MAX not ~0 to test for a 64-bit platform.
