	As I understand both K&R C and the new draft, this program should

	with the parameter "x" provided as an argument.

not quite. foo is defined in `old-style' and hence there's no argument
checking done for calls to foo like the foo(bar).

also, the type of argument x is automatically converted from
`int function' to  `pointer to int function' as stipulated at the
top of p. 218 in K&R2.

hence, there are no errors.
