I'm seeing a steep performance dropoff after I switched from 37b16 to
55. I've compiled 55 with both the default:

CFLAGS    = -O -Wall

and highest:

 CFLAGS    = -O3 -m486 -Wall -Wno-unused -funroll-loops \
  -fstrength-reduce -fomit-frame-pointer -ffast-math
  -malign-functions=2 \
  -malign-jumps=2 -malign-loops=2

optimization flags, (which I see little performance differance
between), but when I un autoframerate a game, it's a lot slower then
37b16 was (not sure what I compiled that with, but most likely would
have been the default).

Also compiled in (these are in my 37b16 binary too): DGA and JOY_I386

The only differance I think is for 55 I had to use the static zlib
that's included, but that shouldn't affect runtime performance.

This is a Slackware 7.1 Linux system. P2 266 Mhz, 128M RAM.

Kangaroo, on xmame (x11) with DGA, auto framerate toggled off:

37b16: 180% during normal gameplay
   55: 106% during normal gameplay

Pingpong, on xmame (x11) with DGA, auto framerate toggled off:

37b16: 150% during normal gameplay
   55: 240% during normal gameplay

And for games where 37b16 barely could do 100% before... well, now
they're unplayable.

Anyone else getting this? Is it a problem on dos/win too? (Although
I would think THAT would have been noticed and fixed really  quick).
Please Cc me with any replies, not on the list. Thanks.

And thanks to the xmame porter(s), I appreciate being able to use MAME
on UNIX.
