Chris,

Thanks for reporting this. I think I've addressed the bash issue by 
downgrading compatibility regarding arithmetic expansion. Apparently 
your system's shell is not POSIX compatible.

I have not looked at your changes to util.c, but I will try to take a 
look. Hopefully someone with a Solaris system available to test could 
help there, as well.

Dan
