* sysdeps/unix/sysv/linux/Makefile ($(objpfx)syscall-%.h $(objpfx)syscall-%.d): Take code from sparc/Makefile to produce a bi-arch file as needed. That's now parameterized by the variable $(64bit-predefine). Use LC_ALL=C for `comm' commands in that rule. No longer conditional on [$(no_syscall_list_h)]. * sysdeps/unix/sysv/linux/sparc/Makefile: Remove replacement rules. (64bit-predefine): New variable. * sysdeps/unix/sysv/linux/x86_64/Makefile: Likewise. * sysdeps/unix/sysv/linux/s390/Makefile: New file. * sysdeps/unix/sysv/linux/powerpc/Makefile (64bit-predefine): New variable. 2002-10-15 Roland McGrath <roland@redhat.com> * sysdeps/unix/sysv/linux/Makefile ($(objpfx)syscall-%.h $(objpfx)syscall-%.d) * login/utmp-private.h: Declare __libc_utmp_lock. * sysdeps/unix/getlogin_r.c (getlogin_r): Take __libc_utmp_lock once call __libc_utmp_jump_table functions directly, instead of using __setutent et al. * sysdeps/unix/sysv/linux/configure.in: Use case instead of if. * sysdeps/unix/sysv/linux/configure: Regenerated.
