One somewhat silly reason that I wouldn't want this: a single ELLCC 
build/install supports all the targets. Currently I have a single include 
directory with target specific headers in target specific subdirectories, e.g. 
include/x86_64/bits/alltypes.h with all the other header files common.

Also, I agree with your previous point that it is nice to go to one place 
(alltypes.h) to find the processor specific types. If you make this change, at 
least keep alltypes.h for reference. ;-)
