Why, yes, it does; thank you.  (I shoulda remembered that...) 
Unfortunately, this is not a solution for me (yet) because:

RE: Problems with GCC-3.4.4-2 (exp) ?
http://www.cygwin.com/ml/cygwin/2006-11/msg00512.html
(debugging symbols/specs file?)

and

"RE: Status of gcc 3.4.4-2"
http://www.cygwin.com/ml/cygwin/2006-09/msg00269.html
(specifically: "...but I'll have to roll a fresh package to fix a couple
of bugs
that showed up")

and

"RE: Requesting an updated gcc-mingw-g++ package to match
gcc-g++-3.4.4-2 (PR24196)"
http://www.cygwin.com/ml/cygwin/2006-10/msg00220.html

(OT: it appears that the mingw project does not have ANY releases that
incorporate this fix; looks like I'll have to roll my own for THAT
environment.)

P.S.  It's my understanding that this change (to std::string) would
constitute an ABI change of the underlying C++/STL runtime library on
cygwin.  Thus, any C++ packages -- or at least, those that are NOT
compiled with -nostdlib -- would have to be recompiled (and version
bumped?) once a g++ with this change was promoted to curr:  Right?

Fortunately, there aren't many of these: libncurses++, xerces, groff,
and the various octave stuff is all that comes to mind -- and octave
already requires binary clients to use g++-3.4.4-2 IIRC.  Oh, and pcre's
libpcrepp. <g>
