This is how you do it.  Just make the appropriate adjustments for the
mega part.

Also, look at the C startup module (gcrt1.S) found in the library
source for more information on how things work.

Thanks to Jason Kyle and Ludovic COURTES I succeded to initialize RAM
size, stack pointer, MCUCR and watchdog control register at link time,
so You won't get strange link error messages if You use ext. memory
and large variables.

Also You don't have to init. stack, MCUCR and watchdog from code.

I attach to this mail the makefile and local linker script file that
do all this.

Thanks to everybody who responded to my question.
