[aprssig] APRS IS weirdness

Rogue forks of open source code might have the potential to introduce new
problems, but it'd be hard to get anything done in open source without them.
I'd never have gotten aprsd to run on my 64-bit Alpha if I didn't have
access to the source, and I'm sure supporting a small minority of 64-bit
users wasn't a high priority for the developers.

And for what it's worth, it doesn't take access to source code to make most
programs do bad things!

aprsd certainly did this also, and its long deployment history makes the
main
fork an unlikely cause, it is possible someone modified the source code and
runs
it on one server causing the problem. An unspoken 'benefit' of open-source!
