Variable: c-recognize-typeless-decls
c-recognize-typeless-decls is a buffer-local variable defined in
cc-engine.el.gz.
Documentation
Non-nil means function declarations without return type should be
recognized. That can introduce an ambiguity with parenthesized macro
calls before a brace block. This setting does not affect declarations
that are preceded by a declaration starting keyword, so
e.g. c-typeless-decl-kwds may still be used when it's set to nil.
