Problems Compiling on Solaris 2.7

[Paul Farrall]

I'm trying to compile swarm 2.1.1 on Solaris 2.7 and it's not going well.  
I've got all the support packages installed and after fixing some
problems, I've now got swarm to compile up to the java stuff, where it
crashes.  Make output is below.  If anyone knows what this error is about
or how to fix it, I'd really appreciate the help.

Thanks,
Paul Farrall
