That was not enough when I first found the problem: when a native
method was called, a float would be pushed onto the stack, but then
the native code compiled by gcc would try to load a double (or so it
seemed to me).  I'm not 100% sure about it right now, though, I have
noticed that quite a long time ago, and worked around the problem in
another way.  Maybe I'll have time to revisit this issue next week.
