False.  See 11.2 "Scope of externals":

	Identifiers declared "static" at the top level in external
	definitions are not visible in other files.

Any declaration outside the definition of any function with "static" omitted
declares an "extern" something, which is static in the sense of not being
"auto" but not static in the sense of being "static"; it's visible in other
files.
