Dist getopt sources
Richard Kettlewell [Sun, 21 Nov 2010 20:15:50 +0000]
Restore option parsing under Windows.
Swiped the getopt sources from GCC 4.5.0 and modified them slightly to
build on Windows. This commit doesn't attempt to support Unix
platforms without getopt_long() but that wouldn't be especially hard
(although all the mainstream ones have it anyway now).

Why does that manage() call need explicit namespace qualification but

speedtest program
Richard Kettlewell [Sun, 21 Nov 2010 00:40:29 +0000]
Furtle with sign handling.
Doing the same in Fixed_mul seems to throw things off, presumably
there is an alignment question to answer.
Richard Kettlewell [Sun, 21 Nov 2010 00:08:50 +0000]
Align square subroutine.
Did NOT align iterloop, it makes it worse! Perhaps branch density too high.
Richard Kettlewell [Sun, 21 Nov 2010 00:05:08 +0000]
We have a register spare for the iteration count
Richard Kettlewell [Sun, 21 Nov 2010 00:00:30 +0000]
As recommended by optimization guide, spill to memory rather than xmm
registers. It really does seem to help - GPR<->XMM transfers are
expensive!

Restrict Fixed64 to actual iteration; it cannot represent large enough
integers to do all the other work, which we therefore keep in Fixed.

Smooth coloring for the fixed point version. Cheats by converting
r^2 to double, so might get crufty at high magnifications?
