Update.
2002-12-16 Jakub Jelinek <jakub@redhat.com> * sysdeps/unix/sysv/linux/i386/socket.S: Use CENABLE and CDISABLE macros instead of doing the calls directly. * sysdeps/unix/make-syscalls.sh: Add ptw-*.$o target name to rules. * Makerules ($(+sysdir_pfx)sysd-rules): Emit rules for ptw-% targets. 2002-12-16 Jakub Jelinek <jakub@redhat.com> * sysdeps/i386/fpu/bits/mathinline.h: Backout last change. * sysdeps/ieee754/bits/nan.h: Likewise. * sysdeps/unix/sysv/linux/ia64/syscalls.list (__syscall_open, __syscall_wait4, __syscall_ioctl, __syscall_write): Add.
