[Bug libstdc++/17315] Strange compile-time regression in cpp against gcc3.4.1

Yes, Giovanni, I agree that this kind of test is worth doing. Just passing 
--enable-libstdcxx-allocator=new at configure time suffices. The viceversa 
would be also useful, that is, passing --enable-libstdcxx-allocator=mt to 
3.4.1 configure. However, again, please remember that the user, in general, is 
*not* supposed to preprocess with 3.4.1 and compile/link with 3.5.0 (or much 
more generally, use an allocator type at pre-processing time and a different 
one at compile/link time), *very* bad things can happen... ;) 
Also, please consider that mt_allocator is more complex and *is* expected to 
be more challenging for the compiler: its performance are *much* better, no 
free lunch... ;)
