Adjust return statements. * include/time.h (__tzfile_compute): Adjust prototype. 2003-02-01 Jim Meyering * time/tzset.c (__tz_convert): Remove dead code; __tzfile_compute always returns 1. 2003-01-31 Steven Munroe * sysdeps/unix/sysv/linux/powerpc/powerpc64/fe_nomask.c [!__ASSUME_NEW_PRCTL_SYSCALL]: Noop prctl syscall and set ENOSYS. 2003-01-31 Steven Munroe * sysdeps/unix/sysv/linux/powerpc/powerpc64/getcontext.S [!__ASSUME_NEW_RT_SIGRETURN_SYSCALL]: Generate ENOSYS stub. * sysdeps/unix/sysv/linux/powerpc/powerpc64/makecontext.S [!__ASSUME_NEW_RT_SIGRETURN_SYSCALL]: Likewise. * sysdeps/unix/sysv/linux/powerpc/powerpc64/setcontext.S [!__ASSUME_NEW_RT_SIGRETURN_SYSCALL]: Likewise. * sysdeps/unix/sysv/linux/powerpc/powerpc64/swapcontext.S [!__ASSUME_NEW_RT_SIGRETURN_SYSCALL]: Likewise. 2003-01-31 Steven Munroe * sysdeps/unix/sysv/linux/configure.in: Change arch_minimum_kernel back to 2.4.19 for powerpc64. * sysdeps/unix/sysv/linux/kernel-features.h (__ASSUME_NEW_PRCTL_SYSCALL): Define for powerpc64. (__ASSUME_NEW_RT_SIGRETURN_SYSCALL): Define for powerpc64. 2003-02-01 Ulrich Drepper * wcsmbs/wcscpy.c (wcscpy): Add alternative implementation for platforms with strange alignment requirements on wchar_t. --- wcsmbs/wcscpy.c | 35 +++++++++++++++++++++++++---------- 1 file changed, 25 insertions(+), 10 deletions(-) (limited to 'wcsmbs/wcscpy.c') diff --git a/wcsmbs/wcscpy.c b/wcsmbs/wcscpy.c index aeb8abb..2e52a6c 100644 --- a/wcsmbs/wcscpy.c +++ b/wcsmbs/wcscpy.c @@ -1,4 +1,4 @@ -/* Copyright (C) 1995, 1996, 1997 Free Software Foundation, Inc. +/* Copyright (C) 1995, 1996, 1997, 2003 Free Software Foundation, Inc.
