I have been trying to work with the bison folks to try and find out why
it keeps hanging on checking for java with gcj installed and this is
where it has gotten so far.

Any ideas.

Did you cause the SIGXCPU)?  For example, do you have "ulimit -t" set?
(Regarding SIGPWR, I don't know what it is...).

So it looks like a problem invoking ecj1 (the Java->bytecode compiler of
GCJ), and not an easily solved one.  You probably should report it to
your Linux distribution.
