	* libio/Makefile [$(versioning)=yes] (routines): Add oldiofopen and
	oldfreopen.

+/* An fstream can be in at most one of put mode, get mode, or putback mode.
+   Putback mode is a variant of get mode.
+
+   In a filebuf, there is only one current position, instead of two
+   separate get and put pointers.  In get mode, the current position
+   is that of gptr(); in put mode that of pptr().
+
+   The position in the buffer that corresponds to the position
+   in external file system is normally _IO_read_end, except in putback
+   mode, when it is _IO_save_end.
+   If the field _fb._offset is >= 0, it gives the offset in
+   the file as a whole corresponding to eGptr(). (?)
+
+   PUT MODE:
+   If a filebuf is in put mode, then all of _IO_read_ptr, _IO_read_end,
+   and _IO_read_base are equal to each other.  These are usually equal
+   to _IO_buf_base, though not necessarily if we have switched from
+   get mode to put mode.  (The reason is to maintain the invariant
+   that _IO_read_end corresponds to the external file position.)
+   _IO_write_base is non-NULL and usually equal to _IO_base_base.
+   We also have _IO_write_end == _IO_buf_end, but only in fully buffered mode.
+   The un-flushed character are those between _IO_write_base and _IO_write_ptr.
+
+   GET MODE:
+   If a filebuf is in get or putback mode, eback() != egptr().
+   In get mode, the unread characters are between gptr() and egptr().
+   The OS file position corresponds to that of egptr().
+
+   PUTBACK MODE:
+   Putback mode is used to remember "excess" characters that have
+   been sputbackc'd in a separate putback buffer.
+   In putback mode, the get buffer points to the special putback buffer.
+   The unread characters are the characters between gptr() and egptr()
+   in the putback buffer, as well as the area between save_gptr()
+   and save_egptr(), which point into the original reserve buffer.
+   (The pointers save_gptr() and save_egptr() are the values
+   of gptr() and egptr() at the time putback mode was entered.)
+   The OS position corresponds to that of save_egptr().
+
+   LINE BUFFERED OUTPUT:
+   During line buffered output, _IO_write_base==base() && epptr()==base().
+   However, ptr() may be anywhere between base() and ebuf().
+   This forces a call to filebuf::overflow(int C) on every put.
+   If there is more space in the buffer, and C is not a '\n',
+   then C is inserted, and pptr() incremented.
+
+   UNBUFFERED STREAMS:
+   If a filebuf is unbuffered(), the _shortbuf[1] is used as the buffer.
