2002-08-29  Ulrich Drepper  <drepper@redhat.com>

	* libio/fileops.c (_IO_new_file_fopen): Recognize new mode specifier
	'm' to enable mmap I/O.
	* libio/libio.h (_IO_FILE): Rename _blksize field to _flags2.  The
	former wasn't used (anymore?).
	(_IO_FLAGS2_MMAP): New define.
	* libio/genops.c (_IO_no_init): Initialize _flags2 field.
	* libio/iofopen.c (__fopen_maybe_mmap): Use mmap callbacks only if
	_IO_FLAGS2_MMAP bit is set.
	* libio/iofdopen.c (_IO_new_fdopen): Recognize 'm' mode specifier.
	Enable mmap-using mode only if 'm' was set.
