The more I look at the assembly, the more it seems to differ from the
source. But I did generate it by changing the -c into -S in the output
of make -n, so it ought to be ok.

Yes, I was wrong about that (so I'll have to look at why the -O2 version
is working in the first place), but the difference between the two
versions is still there and I hope I saw that correctly.

I did find a complete assembler document on compaq's website in the mean
