 It come to me, and the Debian BTS (
 Presumably it also went into the gcc GNATS system.
 The address looks kind of funny...

 The assembler code appears to be exactly the same on gnat 3.14p,
 where it works. In fact, I think the whole file is the same.

 I suspect that support for any assembler code is badly broken, but my
 knowledge of assembler code in Ada is somewhat flakey. I tried moving
 the assembler code to me source code, but it stopped working even with
 gnat 3.14p, which was perviously working.
 It wouldn't surprise me if the assembler code is working, but
 for some reason that parameters aren't getting passed to/from
 the Ada code.
 At one stage I did look at this using a debugger and viewing
 the assembler code, but I couldn't see anything that looked
 obviously wrong.

 Nothing wrong that I am aware of.

 Create interfaces to the C-functions?
 Use gnat 3.14?
 Sorry, these are the only two solutions I know of (not tested the first
 one myself).
