Well this would cause differences in behavior from users which wouldn't 
be immediately obvious if they are set at 0 in the mint.cnf.  Would make 
supporting problems more difficult.  That's why I suggested the binutils 
make a sane default but really I don't know what a sane default is.  I 
never really thought a program would need more than 64KB of stack space 
but G++ easily proves me wrong ;)  I guess I think small ;)
