	As far as I know, the following code is legal, and it works on
    all the machines I have ever used.  It is not neccesarily portable
    everywhere, since some machines may not like executing in the
    data segment, but then again, if you are putting machine code in
    an array and executing it, it isn't portable code in *any* case.

char foo[BIGNUM];
main()
{
        int result;

	/* code to put machine code into foo[] */

	result = (* (int (*)()) foo)();
}
