I didn't know the answer, but I did know how to get the answer. 
A program called "cdecl" comes in very handy at these times.
In the following script, I typed the first line, it answered with the second.

Script started on Thu Mar  8 10:00:06 1990

tove:/u/cml(1)% cdecl
declare foo as function returning pointer to function returning int
int (*foo())()
^D
tove:/u/cml(2)% exit

script done on Thu Mar  8 10:00:36 1990

The cdecl program is available from host mimsy.umd.edu (128.8.128.8) via
anonymous ftp in file "cdecl.shar"  (or I could mail it to a desperate UUCP
site :-).  You must have lex & yacc to compile it.
