Oh, and one other thing:

=======================================================
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:

  (1) libncurses++ from ncurses
  (2) libpcrecpp from pcre -- which would actually benefit from this
      upgrade, as the current libpcrecpp is hit by the very bug
      fixed in g++*3.4.4-2 and -3.
  (3) xerces-c -- orphaned, I think, and it appears that no official
      package on sourceware requires: it.
  (4) groff -- but since it provides no libraries, and the C++/STL
      runtime is statically linked into the executable, this is
      no urgent matter
  (5) various octave stuff -- but octave already requires binary
      clients to use g++-3.4.4-2 IIRC, which means they are
      already on "this side" of the ABI change.
  (6) cygwin itself -- BUT cygwin1.dll is compiled IIRC with
      -nostdlib, so no worries there.

=======================================================

So, from my short list, only ncurses and pcre are impacted -- but I'm 
sure I've forgotten some.
