Approved - please apply.

Note:

> +  const char *alises [MAX_NUMBER_OF_ALIASES + 1];

You could set the this just [MAX_NUMBERR_OF_ALIASES] and then ...

> +          for (j = 0; cpu_types[i].alises[j] != NULL; ++j)

test for i < MAX_NUMBER_OF_ALIASES as well as a NULL alias.

Which would save a very small amount of space and is probably 
not worth it.  But it just struck me as odd that you would create
an array with MAX + 1 elements in it.

Cheers
