I've rebuilt using -O2 explicitly in CFLAGS and put it here:

http://www.russet.org.uk/scratch/

Using the benchmarks on the reddit link, it does make Emacs
significantly faster.

@Jostein Kjønigsen could you give these a go and let me know of your
experiences.

@Eli assuming that these binaries address the issue what do I do with
the version number in uploading them to ftp.gnu.org. I don't want to
over-write the existing ones, nor use the same version number.

Apologies all for these difficulties.
