// Two flat FILE imports each declare the SAME libc symbol `absval` via the
// `extern` keyword (the linkage-keyword twin of example 0729's `extern`
// form). The bare-call resolver must NOT count extern authors when deciding
// ambiguity — they are external C symbols, never rerouted by the bare-call
// machinery, so the existing first-wins extern dispatch binds the
// call and a same-name extern collision compiles + runs (prints 7), it does
// NOT error as ambiguous.
//
// Regression (FFI-linkage Part B): `isPlainFreeFn` / `isPlainFreeFnDecl`
// excluded a `extern` body but classified an empty-block `extern` fn as a
// plain free function, so the two extern authors were wrongly counted as an
// ambiguous bare-call collision. Prerequisite for migrating the fn-decl
// `extern` path onto `extern`.
