Sun Dec 22 00:01:27 1996 Ulrich Drepper <drepper@cygnus.com> * inet/getnetgrent.c: Reformat copyright. * inet/getnetgrent_r.c (__internal_endnetgrent): Correct comment. (__internal_getnetgrent): Rename to __internal_getnetgrent_r as required in change nis/nss_compat/* at Thu Dec 19 14:24:50 1996. Reported by Thorsten Kukuk <kukuk@weber.uni-paderborn.de>. * nss/nss_files/files-netgrp.c: Fix typo. * login/utmp_db.c: Comment out unused variables. * misc/tst-dirname.c: Provide prototype for main (for now). * new-malloc/mcheck-init.c: Include <mcheck.h>. * new-malloc/obstack.c: Provide real prototypes. * resolv/base64.c (b64_ntop): Use size_t as type of `i', not int. (b64_pton): Likewise for `tarindex'. * resolv/nsap_addr.c (inet_nsap_addr): Add cast to prevent warning. * stdio-common/Makefile: Add CFLAGS-vfprintf.c to prevent warning. * stdio-common/printf-parse.h: Remove definition of MIN and MAX. * stdio-common/printf-prs.c: Include <sys/param.h> to get MIN and MAX. * stdio-common/vfprintf.c: Likewise. * stdlib/gmp-impl.h: Only define MIN and MAX if not already done. * stdlib/tst-strtol.c: Don't use -2147483648 as unsigned long value. * sysdeps/generic/Makefile ($(subdir)=string): Define CFLAGS-wordcopy.c to prevent warning. * sysdeps/generic/mul_n.c (mpn_mul_n): Don't define as inline. * sysdeps/generic/wordcopy.c: De-ANSI-declfy. * sysdeps/i386/Makefile ($(subdir)=elf): Define CFLAGS-rtld.c to prevent warning. * sysdeps/i386/dl-machine.h: Correct copyright. * sysdeps/unix/closedir.c: Likewise. * sysdeps/unix/dirstream.h: Likewise. * sysdeps/unix/opendir.c: Likewise. * time/tzset.c: Add prototype for __tzset_internal. * sysdeps/gnu/utmpbits.h (enum utlogin): Comment out since the way it is supposed to work is not yet known. (struct utmp): Remove ut_login and ut_syslen field for now. Sat Dec 21 16:23:54 1996 Ulrich Drepper <drepper@cygnus.com> * time/strftime.c: Fix another bug in handling flags made it impossible to use the `-', `_', or `0' flag.
