Tue Jan 7 09:48:15 1997 Andreas Jaeger <aj@arthur.pfalz.de> * signal/sigempty.c (sigemptyset): Correct typo: Empty set should have all bits zero. Tue Jan 7 23:44:39 1997 Ulrich Drepper <drepper@cygnus.com> * inet/gethstbynm.c: Include additional headers for additional code in nss/digits_dots.c. * inet/gethstbynm_r.c: Likewise. * inet/gethstbynm2.c: Likewise. * inet/gethstbynm2_r.c: Likewise. * nss/digits_dots.c: New file. Handle dotted pair notation for gethstbynm functions. * nss/getXXbyYY.c: Include digits_dots.c to get extra code for handling dotted pair notation. * nss/getXXbyYY_r.c: Likewise. Patches by HJ Lu. * resolv/nss_dns/dns-host.c: Don't handle dotted pair notation. * io/getwd.c: Optimized a bit. * signal/signal.h: Always declare __sysv_signal. * sysdeps/generic/setenv.c: Add some portability code. * sysdeps/unix/sysv/fcntlbits.h: Update copyright. * sysdeps/unix/sysv/linux/fcntlbits.h: Add definitions from kernel to avoid using kernel headers. * sysdeps/unix/sysv/linux/alpha/fcntlbits.h: New file. Alpha specific version. * sysdeps/unix/sysv/linux/syscalls.list: Add sys_mknod. Don't mark sigreturn as EXTRA. * sysdeps/unix/sysv/linux/ustat.c: Declare __syscall_ustat. * sysdeps/unix/sysv/linux/alpha/ustat.c: New file. Alpha version. Tue Jan 7 09:48:15 1997 Andreas Jaeger <aj@arthur.pfalz.de> * io/fts.c (fts_alloc): Add const to second parameter of function. * io/Makefile: Change CFLAGS-fts.c and define CFLAGS-ftw.c to prevent warnings. * signal/sigfillset.c: Include <string.h> for memset declaration. Tue Jan 7 11:14:32 1997 Miles Bader <miles@gnu.ai.mit.edu> * sysdeps/generic/setenv.c: Fix portability problems. Tue Jan 7 02:10:17 1997 Ulrich Drepper <drepper@cygnus.com> * posix/getopt.c (_getopt_internal): Don't reset __getopt_initialized after the last option was seen. Mon Jan 6 15:30:21 1997 Ulrich Drepper <drepper@cygnus.com> * elf/elf.h (DT_EXTRANUM): Set to 3 since 0x7ffffffd is used.
