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.

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

More exact example:
.h:
extern int i;
.cpp:
int i; // ok
