I agree.  Sorry, I've been travelling, and couldn't reply.   It appears
to me that most of the problems on alpha are because sizeof(size_t) >
sizeof(int), but, as you say, there are some other problems (perhaps
brought out in the x86 bootstrap), and the little bit of time I had
to look at it didn't allow me to separate the two.
