Possibly, libgcj just doesn't work without threads - I doubt anyone has 
tested a "no threads" libgcj configuration for a while. In any case, 
Java is not very useful without threads - did you try it with posix 
threads enabled? HPUX has those, right? :)

This shouldn't really be needed. There is an autoconf macro to do it 
already, so libjava's configure.ac should be defining it.
