Once again, ``cdecl'' to the rescue:

> char *f1()  { return("1"); }
> char *f2()  { return("2"); }
> /* decl array of ptrs to fns returning ptr to char */
> char *(*funcs[2])() = {f1,f2};
> /* decl ptr to array of ptrs to fns returning ptr to char */
> char *(*(*pfuncs)[])() = funcs; 
> /* "junk.c", line 47: warning: illegal pointer combination        */
> /* I can't get that to compile without a warning but it works ok. */

% cdecl << eof
declare pfuncs as pointer to array of pointer to function returning pointer to char
eof
Warning: Unsupported in C -- Pointer to array of unspecified dimension
char *(*(*pfuncs)[])()
%

It not only gives you the required declaration, it even tells you why
the compiler won't like it!  :-)
