mmm, ...
we need to make sure that the native code compiler don't make use of these
extra instructions though. from a quick glance at ocaml-3.01/asmrun/arm.S, i
don't think that is so, after all this file is pretty short, but then i know
nothing about arm assembly. Could you please look at it (it is 338 lines only)
and check that no armv4l instructions are used ?

Thanks, if it builds correctly, then i will close the bug on monday, and
forward the patch upstream.
