Your compiler is right of course in taking the first as valid. A you say,
this may not be given in K&R, but I found some equivalence rules in another
book : "Advanced C: food for the educated palate", by N. Gehani, Computer
Science Press (ISBN 0-88175-078-6). You can find out this way:

     foo             : array of pointers to functions returning int
=>   foo[]           : pointer to function returning int
=>   *foo[]          : function returning int
=>   (*foo[])()      : int

and thus you have the right syntax.

I posted this rather than replying as you are not on UUCP and I have already
experienced that mail sent through complex channels does not reach its
destination easily.
