oops, smaller, but not faster, though the difference is just a few %

Yes, none of the others produced working executables as is.

There is support called arm-crunch-unwind.patch in the later tarballs
that is independent of the other patches and it should apply OK to the
earlier GCC versions too.
You can see it my most recent complete set under
http://martinwguy.co.uk/martin/crunch/gcc-4.3.2-patches
though this isn't prodution quality (sometimes Internal Compiler Errors)
If you'd like to try adding that patch and running some tests with
unwinds,  I'd be glad to hear of your results .
