WTF? Rick suggested removing that configure message that you need to 
explicitely override its quite sane default to refuse work with gcc4, 
because at least one platform (the most common one) has problems with it.

I was against removing this safety valve, because it does _nothing_ to 
help users understand why QEmu does not compile.

The situation now: gcc4 is not supported, but might work. configure tells 
you as much, and even gives you rope to try nevertheless.

The situation suggested: configure silently ignores the fact that gcc4 is 
the current compiler, and in some (not at all rare) cases, the compilation 
just fails without a clue.

So I absolutely _fail_ to understand what you thought, implying that I was 
restricting platform variability.
