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.
