I wish you were right... Alas, I stand by my words : the attitude of a 
minority of Debian developpers is on the line of "If it was hard to 
write, it should be hard to use". Unfortunately, this minority has a 
serious overlap with the *very good and active* category...

Case in point : I distinctly reember reading a convoluted thread in one 
of the Debian lists about this /etc/alternative issue for gcc... Was I 
drunk ? Or what ?

Didn't work last time I tried : you may do that at *configure* step. In 
the case of a GCC4 kernel, you have to :
- configure and make with gcc 3.3 (--cc=gcc-3.3 goes into 
config-host.mak. What the host-cc does is fairly well obscur to me (got 
lost in the Makefile/source code), and was undocumented last time I 
pored over Fabrice's pages).
- make clean in the kemu directory
- re-make with GCC 4 : this recompiles only the kqemu part.

If you can suggest a more steamlined way, I'd be happy to hear from it, 
and even more happy to read it on Fabrice's pages or somewhere in the 
documentation...
