Ignore exit status from diff. * configure.in (enable_check_abi): Document possible value "warn". Change default to no for now. * configure: Regenerated. * sysdeps/unix/Makefile ($(objpfx)stub-syscalls.c): Emit stub_warning macro calls and a #include <stub-tag.h> at the end. * Makerules ($(objpfx)stubs): Tweak sed commands. * sysdeps/unix/sysv/linux/syscalls.list: Use - rather than EXTRA in caller column for *xattr syscalls, since they are in sysdeps/generic. * sysdeps/unix/sysv/linux/i386/setfsuid.c: setfsgid -> setfsuid * sysdeps/unix/sysv/linux/i386/setfsgid.c: setfsuid -> setfsgid 2003-03-26 Roland McGrath <roland@redhat.com> * Makerules (check-abi-config): Use /thread instead of /tls when use-thread and not just use-tls is set. * Makerules (update-abi): Put quotes around $(update-abi-config). * elf/Makefile (check-abi): Depend on check-abi-ld. (update-abi): Depend on update-abi-ld.
