Hey guys,

Seems like this may be a g++ problem for 4.2.X?

I get a result of '1' for function c() using the following:
g++ 4.1.2 		on Fedora/x86_64
g++ 3.4.2 		on Aurora/Sparc64
g++ 4.1.2 		on Syllable/x86
llvm-g++ 4.0.1 	on Fedora/x86_64

but I get a result of '0' for:
g++ 4.2.3 		on Ubuntu/x86

Huh, really... all the versions of g++ I have on my system mess this up.
