It may be desirable to use GPL+exception, to demangle GCJ stack-traces.
Currently, we filter stack traces through a forked c++filt, because
of the license.  On the other hand, there has been talk that it would
be better anyway (though more work) to use the dwarf2 eh-unwinding code.

But at least in the short term, it would be better to be able to
link the demangler directly in to libgcj, without license contamination.
