Does this mean that some programs wont run on CPUs pre 686  (ie. 386, 486,
586) ?

I'm OK with it.  I have built and installed powerpc cross-compilers and even
done a Canadian cross for the cygwin environment.  I think that getting rid
of the H-* layer is a very good idea in general.  I now understand why it is
there.  Will getting rid of it make it harder to support multiple hosts using
a shared file server ?  Since this scenario is not very common I guess it
would be easy for a system administrator to add the extra directory layers to
represent the multiple host architectures.

Do we ?  I don't know that.  How can and i586 be the same as an i686 ?

Thanks,
