Other tips


unsigned int generates faster/smaller code than int on all platforms except sh5
bad:
             int i;
             for (i = 0; i < 10; ++i)...
good:
             unsigned int i;
             for (i = 0; i < 10; ++i)...

unitialized static variables are 0
bad:
             static struct *foo = NULL;
good:
             static struct *foo;   /* = NULL */
