More exact example:

.h:

extern int& i;

.cpp:

int& i; // ok

extern int &i;
is valid though.  Note in C, int i; is a tentative definition while in C++,
there is no such thing as a tentative definition so it is normal definition and
therefor since it is a reference type variable, it has to be initialized.

t.c:1: error: 'i' declared as reference but not initialized

Why do you think this is valid code?  Reference variables have to be
initialized.
