For me its also the fact that I'm "used" to it. The xemacs/gcc combo
instead of the vstudio stuff.

heh, folks keep threatening to use said "posix" subsystem to port
libferris to the evil empire but I'll believe that when I see it.

This is one of the major ones. I have seen folks strcpy() to a const
char* on the stack before, I always like a little entropy in my life,
but that is just too much fun. I guess this one depends on how
comfortable you are with the other folks who have cvs write access.

The lack of shared libraries is a real kicker, but I definately see a
case for a tiny single app embedded system without MMU, its just when
the marketoids start adding stuff and soon you have 6-8 people hacking
the code and many apps to run and the mess starts piling up.

Ah, obviously not an Amiga programmer (-; Or an asm coder for that
matter: Why should I malloc() the RAM, I can generate a unused address
myself!
