The idiocy of having a system perfectly able to handle alternative 
packages ... except when it isn't, for reasons too obscure to be 
understood by a 31-year computer user (yes, I wrote my first Fortran 
program in 1974..) when he isnt a dedicated system maintainer. I *use* 
computers, dammit, I have not too much time to play system administrator....

That's exactly what I was trying to do. Debian has switched to GCC 4 for 
kernels. But (parts of) QEMU) need gcc 3.4. Hence the raindance..

I missed the doc-"howto" for these options. Last time I tried, I ended 
up with "Incorrect module format" errores and/or bad compilations 
errors. I gave up and learned to change compilers...

No such thing on Debian. They have a (supposedly) nice system 
("module-assistant") for compilong out-of-tree modules... which I never 
quite figured out. When I need an out-oft-tree kernel (which is rare 
nowadays), I still roll my own kernel, à la Neanderthal...
