PATCH: libstdc++/7922

[Loren James Rittle <rittle at latour dot rsch dot comm dot mot dot com>]

I did quickly study how this problem was fixed over the years (even
though I have fixed similar myself a few times).  Since each point of
lookup occurs exactly once, I chose this fix verses the introduction
of 4 new mirror/forwarding typedefs (the other style which was used to
fix it in the library).  Tested on i386-unknown-freebsd4.6 (on
mainline in already bootstrapped tree and on 3.2.X branch by building
libstdc++-v3 against installed compiler) and by PR submitter in his
environment; applied to mainline and 3.2.X branch (since regression).

[ext/rope.cc actually finds the bug when testsuite run with -pedantic
 flag, thus no new test case deemed required IMHO.  Instead, we should
 consider enabling a pass of the library testsuite with that flag OR
 just encourage us developers to run with that flag every now and
 then.  For good measure, I will do so on mainline.]

	* include/ext/stl_rope.h (rope<>): Qualify dependent names
	with `typename'.
