That made it, thanks. I had to gently add

#undef MCU_AT91SAM9260
#undef MCU_AT91SAM9XE
#undef MCU_AT91SAM7S
#undef MCU_AT91SAM7SE
#undef MCU_AT91SAM7X
#undef MCU_AT91SAM7X256
#define MCU_AT91R40008

it in the following files:
/arch/arm/dev/usart0at91.c
/arch/arm/dev/usart1at91.c
/arch/arm/os/nutinit.c

after this I could compile NutOS and the applications.

The question is why this happened. I simply downloaded a fresh 
ethernut-4.8.4.tar.bz2 and choose the ethernut30e.conf that comes by 
default as the configuration file (just as I do with 4.6.4). Then I make 
sure that the CPU selected is the AT91R40008, and only that one.

So, the question is, am I missing something or is this somehow a bug?

Well, 4.9.6 does not compile for me either, with problems that I think 
are also related to unproper definition of the MCU. At least this one is 
solved by undefining MCUs

but after solving this new ones appear...

So, am I missing something or is there any issue around?
