All parameters need a nonempty list of declaration specifiers in a parameter type list, which y doesn't have in that case. Implicit int in C90 (removed in C99) means that list could just be "const", for example, but not completely empty. That the first parameter in a parameter type list must have some *non-attribute* declaration specifier is documented in "Attribute Syntax" along with the ambiguity this resolves. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=37874
