  Not sure yet:

  That bit's fairly easy.  I'll take a look at the approach and see if it's
different from how I've done it.  (Needs shared libstdc++ and libgfortran as
well to really be worthwhile in the cygwin distro, I think).

  Don't know what these problems really are, will check and import patches
if useful.

  I'm also building dw-2-only versions of gcc4, btw.

  I hope to prepare a test release over the next few weeks while also
sending patches upstream to switch gcc over to shared libs and dwarf 2 on
cygwin target - I figure that we probably just have to live with the
throwing-from-win32-callbacks issue on HEAD FTM and fix it using SEH.  With
your gcc maintainer hat on, does that sound like an approach you'd be happy

Can't think of a witty .sigline today....
