Thanks for the quick answer. That might be the perfect diagnosis. Yes,
I'm using gcc 2.95.2 on an old Debian Potato distribution. I'll try to
play with some compiler (optimization) switches. Sometimes that helps.

What about trying to not use inline ASM when it's not 100% necessary?
Separate ASM modules could sometimes do the job and are easier to
handle. The little call overhead shouldn't be too much on recent CPUs.

BTW Appendix D does not yet point out the gcc 2.95.2 problem.
