Update.

2000-02-08  Andreas Jaeger  <aj@suse.de>

	* sysdeps/unix/sysv/linux/mips/pwrite64.c: Define __libc_* variant
	for cancelation wrapper; use __ASSUME_PWRITE_SYSCALL macro.
	* sysdeps/unix/sysv/linux/mips/pread64.c: Likewise.
	* sysdeps/unix/sysv/linux/mips/pwrite.c: Likewise.
	* sysdeps/unix/sysv/linux/mips/pread.c: Likewise.
