How much work is it to keep the existing design/organisation of gcc as it is
now but make it to be able to read/load in architectural info (hence overiding
the default values of various macros) as the user chooses to ?  If the user
doesn't raise the flag then gcc will be the same as before -- i.e. it should
impose no performance penalties.  I know that reading in this kind of info
will slow the compiler down to a certain extent but I thought that it'll be
nice if the user can at least have a choice.  This feature I guess will of
some help to people who are designing/using new machines/architectures or
simply adding a new processor to an existing family -- this helps/breeds
experimentations -- i.e. everytime you add a new feature to the processor you
just need to modify a single file and don't need to rebuild gcc in order to
test things out.

Oh well, just a thought ...
