2000-01-30 Ulrich Drepper <drepper@redhat.com> * locale/programs/ld-collate.c (struct locale_collate_t): Change type of plane_size and plane_cnt to uint32_t. Reported by Jakub Jelinek. 2000-01-29 Jakub Jelinek <jakub@redhat.com> * sysdeps/unix/sysv/linux/sparc/sparc32/sysdep.h (SYSCALL_ERROR_HANDLER): Optimize. (__SYSCALL_STRING, __SYSCALL_CLOBBERS): Define. Include linux/sparc/sysdep.h. Use a different guard define than linux/sparc/sysdep.h. * sysdeps/unix/sysv/linux/sparc/sparc32/syscalls.list: Remove stubs for inlined syscalls. * sysdeps/unix/sysv/linux/sparc/sparc64/sysdep.h (SYSCALL_ERROR_HANDLER): Optimize.
