Porting Newlib

[Dave Murphy <wintermute2k4 at ntlworld dot com>]

Hi

I've been working with newlib on a couple of embedded systems using Bill 
Gatcliffe's articles for reference.

So far I've managed to get the syscalls working to the point where 
printf, fpriintf(stderr, ...) etc function as expected. Currently I'm  
trying to get cout working without much success.

I thought that the iostream functions used the same low level output 
mechanism as printf and company, going through _write or _write_r as 
appropriate but this doesn't appear to be happening. Is there something 
else I need to do, in addition to setting up the device table, in order 
to support the C++ iostream functions?
