c89 3.3.2.2:
"If the expression that precedes the parenthesized argument list in a
function call
consists solely of an identifier, and if no declaration is visible for
this identifier,
the identifier is implicitly declared exactly as if , in the innermost
block containing
the function call, the declaration "extern int <identifier>();"
appeared."
So the implicit declaration is not supposed to happen when the function
identifier
is surrounded by parentheses, and this is not conforming.
