I'm sorry, but I applied your patch to my local bazar version of cedet 
and the issue I described just remains as is. No change at all.

Apart from stripping my init.el down to the aforementioned 3 lines, I 
now also generated an absolutely bare-bones ede automake project with a 
single program target comprising of the following sophisticated piece of 
code

#include <iostream>
using namespace std;

int main() {
   cout << "Hi there" << endl;
   return 0;
}

I compile the project with 'C-c . C', I close all windows except for the 
one showing the code, I invoke 'C-c . R' once, this pops up an *EDE 
Shell ...* window, splitting the Emacs pane, and saying "Hi there". I 
invoke 'C-c . R' a 2nd time, this pops up another *EDE Shell ...* 
replacing the windows content which previously showed the code, leaving 
me with two identical *EDE Shell ...* buffers displayed in two windows 
on the emacs pane.

To make absolutely sure that the bazar version on my system was not 
somehow contaminated by emacs-built-in stuff, I replaced the string 
"*EDE Shell %s" on line 73 in shell.el by "*xxEDE Shell %s", which in 
turn was actually also the buffers name I got on invoking 'C-c . R'.

Any other idea?

PS.: now how cool is it that there is even a Gnu hello project? I didn't 
know that. And its tar.gz even takes a full 700K. That's something.
