That has a different meaning.  The former declares `foo' as a function.
The latter declares `foo' as a pointer to a function.

        bash$ cdecl
        Type `help' or `?' for help
        cdecl> explain int (*foo(float* ,int (*) (float*)))(float*)
        declare foo as function (pointer to float, pointer to
                function (pointer to float) returning int) returning
                pointer to function (pointer to float) returning int

        cdecl> explain int (*(*foo)(float* ,int (*) (float*)))(float*)
        declare foo as pointer to function (pointer to float, pointer to
                function (pointer to float) returning int) returning
                pointer to function (pointer to float) returning int
