Thanks for the update; I was going to ask about the progress on this.

Out of curiosity, have you done this with cygport yet?

Interesting.  I wonder if this would help with linking libsmokekde and
libkdejava, both of which fail during linking for the same reason.
Perhaps the other compilers should also be built with this flag for the
same reason (and binutils' ld as well)?

- From your notes, I gather that all libs are being built shared.  If so,
that's very good news, and I look forward to seeing this become readily
available.

To that end, a few questions:

1) What progress is being made to get these patches included upstream?
2) How long before gcc-4.3 will be stabilized enough to be generally usable?
3) Could you and/or others working on this keep this list updated on
further progress?
