Ethan,

Can you explain the insecurity a bit more?  Any ideas on a better
construct that won't cause /dev/null to be erased in some cases?  I
just want a solution, it doesn't have to be the one I put in there. :-)

Would it be possible just to do something like "$(AS) --version"
instead, as this code is theoretically just checking for an old version
of as?

John
