There is is problem with MINIX stdio, both the original and the
new one, namely that they use dynamically allocated
io_buf's. 

Shouldn't be a problem I hear you say, shouldn't be visible to the user
etc etc.. BUT: Try this

#include <stdio.h>

FILE *fred=stdin;

main()
{
}

Doesn't work does it ? Should do shouldn't it ?

This has caused me loads of hassle when trying to port UNIX software
to MINIX. I rewrote the MINIX stdio library so it did it properly since
I think THIS SHOULD WORK. Now I'm going to have to do it all again Sigh!!
