No, it does not.

see line 4968

However, wasn't the point of using ToT libtool: to _avoid_ haring off
with quick-n-dirty [*] local patches -- in effect, forking libtool? 
Instead of fixing gcc's local copy, shouldn't this fix -- or a better
one -- instead be submitted to libtool, and then gcc can resync?  (At
least in the medium-to-long term.  For an immediate and temporary fix
for a broken build, as long as it IS temporary...)

[*] As Mike pointed out, the proposed change is not compatible with
older compilers.
