Just to jump in here, I haven't been able to reproduce the problem on
my SunOS 5.8 Generic_108528-14 box, so there's something odd going on.
On my box, /bin/bash --version reports "GNU bash, version
2.03.0(1)-release (sparc-sun-solaris)".

Surely that should be:

/bin/bash -c "test unknown != big -a unknown != unknown"

though I don't think it matters.  Either way, it outputs nothing on my
SunOS 5.8 Generic_108528-1 box, which is as it should be.
