Building gcc v4.0 on Mac OS 10.3.8

[Niko Matsakis <niko@xxxxxxxxxxxx>]

I am attempting to build gcc version 4.0 on Mac OS X 10.3.8, but I am 
having some trouble.

First, I tried to run configure but discovered that I need to upgrade 
my cctools to 528.5.

So I went and downloaded the source and tried to build that, but here I 
fail to build because streams/streams.h cannot be found.

I am reluctant to run the cctools binary installer because I do not 
want to overwrite the cctools that I have currently; I am hoping to 
build from source and keep the executables solely for use with this gcc 
build I am experimenting with.


thanks,
Niko
