* sysdeps/unix/sysv/linux/s390/s390-32/sysdep.h (INTERNAL_SYSCALL,
INTERNAL_SYSCALL_ERROR_P, INTERNAL_SYSCALL_ERRNO): New macros. (INLINE_SYSCALL): Use that. * sysdeps/unix/sysv/linux/s390/s390-64/sysdep.h (INTERNAL_SYSCALL, INTERNAL_SYSCALL_ERROR_P, INTERNAL_SYSCALL_ERRNO): New macros. (INLINE_SYSCALL): Use that. * sysdeps/unix/sysv/linux/x86_64/sysdep.h (INTERNAL_SYSCALL, INTERNAL_SYSCALL_ERROR_P, INTERNAL_SYSCALL_ERRNO): New macros. (INLINE_SYSCALL): Use that. * sysdeps/unix/sysv/linux/sparc/sparc32/sysdep.h: Include dl-sysdep.h. (SYSCALL_ERROR_HANDLER): Define RTLD_PRIVATE_ERRNO variant. (__INTERNAL_SYSCALL_STRING): Define. * sysdeps/unix/sysv/linux/sparc/sparc64/sysdep.h: Include dl-sysdep.h. (SYSCALL_ERROR_HANDLER): Define RTLD_PRIVATE_ERRNO variant. (__INTERNAL_SYSCALL_STRING): Define. * sysdeps/unix/sysv/linux/sparc/sysdep.h (INLINE_SYSCALL): Pass __SYSCALL_STRING to inline_syscall*. (INTERNAL_SYSCALL, INTERNAL_SYSCALL_ERROR_P, INTERNAL_SYSCALL_ERRNO): New macros. (inline_syscall0, inline_syscall1, inline_syscall2, inline_syscall3, inline_syscall4, inline_syscall5, inline_syscall6): Add string argument. 2002-10-24 Roland McGrath <roland@redhat.com> * libio/bug-wfflush.c: New file. * libio/Makefile (tests): Add bug-wfflush.
