[En-Nut-Discussion] Bug in Nut Init?

I noticed a bug in the NutInit function

register volatile u_char * xramend = ((volatile u_char *)0x7FFF);

Doesn't work unless you have some optimisation turned on, because it saves
xramend in a non existent stackframe. (As one should not allocate variables
in naked functions - register or otherwise )

Changing the line to

#define xramend ((volatile u_char *)0x7FFF)

Creates exactly the same code as the above (when it works) but works both
optimised and unoptimised.
