Thanks for your reply. But I am still puzzled by a paragraph in the standard
(http://www.open-std.org/jtc1/sc22/wg14/www/docs/n1570.pdf):

-------------- C11 standard, sec 6.7.6.3, page 134 --------------
14. An identifier list declares only the identifiers of the parameters 
of the function. An empty list in a function declarator that is part of 
a definition of that function specifies that the function has no 
parameters. The empty list in a function declarator that is not part of 
a definition of that function specifies that no information about 
the number or types of the parameters is supplied.

So if I understand it correctly, the function "fn1" does not have any
parameters. Please kindly advise. Thanks.
