GCC 3.4.x => 4.0 compatiblity

[Andrew Muraco]

Well as we speak - im on the verge of grabbing gcc-cvs - the only thing 
that worries me is that right after i build gcc and start building the 
system some major bug or regression in 4.0 will be fixed and illl have 
to basicly start over (its a p2 so its slow)

im going to try and compile with
-march=i686 -Os -pipe -fomit-frame-pointers

and build as little as possible for the time being - probably nothing 
graphical anyways

(glibc and some others are first on the list)

as a side note: http://dev.gentoo.org/~halcy0n/ has some gcc-4.0 patched 
ebuilds for common things which i will be using (glibc and such) to make 
them work with gcc-4.0 so take a look
