Interesting.  I had not noticed that 9vx was building on my machines with:

  gcc -fno-inline -c -g -O3 -MD -std=gnu99 -O2 -march=i486 -pipe

and

  gcc -m32 -c -nostdinc --g -O3 -MD -std=gnu99 -O2 -march=i486 -pipe
-fno-stack-protector -m80387 -mfp-ret-in-387

in other places.  I would have removed -O3 if I had noticed it before.
I'm curious why the "-fno-stack-protector -m80387 -mfp-ret-in-387" was
required?

Ron, did you use any optimization or taken it out completely.  Also, are
you going to add this patch to your repository, or should we handle it on
our end?
