Header file installation

[Mark Mitchell]

Benjamin, Phil Edwards, and I have talked about the G++ header file
situation, and we're thinking we'd like to have the headers installed
in the gcc-lib/arch/version/include directory, instead of in
include/g++-3.  (By the way, that also goes along with a request from
some BSD folks that I talked to at ALS2000.)

The advantages are that it will make `gcc -V' more likely to do
something sensible, and that the `g++-3' bit is very confusing to
users, judging by how often questiosn regarding that come up on the V3
mailing list.

Does anyone have objections to this change?
