2003-06-25 Ulrich Drepper <drepper@redhat.com> * sysdeps/unix/sysv/linux/cris/sysdep.h (INLINE_SYSCALL): Cast result to long int so that extensions to long long int work. Patch by Uwe Reimann <libc-alpha@pulsar.homelinux.net>. 2003-06-19 Jakub Jelinek <jakub@redhat.com> * elf/ldconfig.c (main): Use add_system_dir instead of add_dir. * sysdeps/generic/dl-cache.h (add_system_dir): Define. * sysdeps/unix/sysv/linux/x86_64/dl-cache.h: Include sparc dl-cache.h. * sysdeps/unix/sysv/linux/s390/dl-cache.h: New file. * sysdeps/unix/sysv/linux/mips/dl-cache.h: New file. * sysdeps/unix/sysv/linux/powerpc/dl-cache.h: New file. * sysdeps/unix/sysv/linux/sparc/dl-cache.h: New file.
