At block scope, function definitions are not permitted.  At file scope,
a function definition cannot start with 'T('; it requires at least a
type name and an identifier.  At least that's the case since C99 -- and
on the other hand, some (most?) compilers use a C90-compatible grammar
that permits implicit-int definitions and diagnoses them separately.
