Ulrich Drepper 279eb600d9 Update.
1998-04-07  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>

	* sysdeps/unix/sysv/linux/_G_config.h (_G_stat64): Define to
	stat64.
	(_G_OPEN64, _G_LSEEK64, _G_FSTAT64): Use namespace clean
	functions.
	* sysdeps/unix/sysv/linux/alpha/syscalls.list: Add __lseek64 alias
	for __llseek.
	* sysdeps/unix/sysv/linux/sparc/sparc64/syscalls.list: Likewise.
	* sysdeps/unix/sysv/linux/llseek.c: Likewise.
	* sysdeps/generic/lseek64.c (lseek64): Rename to __lseek64, and
	make it a weak alias.
	* posix/unistd.h: Declare __lseek64.

	* libio/fileops.c (fstat) [_LIBC]: Use namespace clean function.
	(_IO_file_stat): Fix typo.
	(_IO_file_xsgetn): Update fd->_offset.  Read a multiple of the
	block size from the file.  Use __mempcpy if _LIBC.
