If you compile the file before.cpp, with and without defining the
PRINT_TYPE_INFO_BEFORE define, the type_info::before() function will not
generate the same output.

Here are the steps to reproduce the bug:

In this case A is not before B: typeid(A).before(typeid(B)) == false

> g++ before.cpp -o before
> ./before
A is before B: 0
typeid(A).name(): 1A
typeid(B).name(): 1B

In this case A is before B: typeid(A).before(typeid(B)) == true

> g++ -DPRINT_TYPE_INFO_NAME_BEFORE before.cpp -o before
> ./before
typeid(A).name(): 1A
typeid(B).name(): 1B
A is before B: 1
