Declaring a variable static in b.h would not make the variable accessible
outside b.h. So even if you include b.h in some other file a.h, then its
legal to have a variable with same name.
As pointed by Nico, its not good to employ such coding practices... you can
think of namespace if you cannot avoid the use case.
