scope of a varible in gcc source code

Hi,
    'vect_dump' is variable of FILE type. That is
declared in tree-vectorizer.c

When I tried to access it from the file
tree-scalar-evolution.c, I got installation error.

My question is how to enable vect_dump variable
access-able in every file including
tree-scalar-evolution.c,
toplev.c....passes.c........etc

In which file I have to declare that variable?

If I move that declaration, to other file, from
tree-vectorizer.c , will I need to declare that
variable as extern in tree-vectorizer.c????
