That would be my guess too, but I don't have gcc-4.2.x installed to 
check, it would be useful if someone who has that compiler can check if 
the Config test case builds in C++03 mode, and if so whether 
<forward_list> is genuinely usable (or whether our test is too simplistic).

There are also some GCC versions which support C++11 features in C++03 
mode, but complain so loudly about doing so that the feature is 
effectively unusable.
