We use fdlibm to do string->double conversions. I imagine that step
is fine (though of course only debugging will show the truth). It is
possible that we introduce problems in the other steps, since gcc
doesn't fully respect Java semantics. Failures like this, if that is
what they are, can just be ignored (disabled) for now; we can't fix
these problems in the 3.1 timeframe.
