We ran into an interesting problem with cfont 2.0.  It seems that it doesn't
like an allocation of automatic variable within an inline function.  The
following code illustrates the problem.

    #include <stream.h>

    class Foo
    {
        public:
	    Foo ();
	    void doit ();
    };

    Foo::Foo ()
    {
    }

    inline void Foo::doit ()
    {
        char buf[1024];

        sprintf (buf, "Hello, world\n");
        cout << buf;
    }

    main ()
    {
        Foo bar;

        bar.doit ();
    }

The compiler comes back with the message:

    "test.c", line 27: sorry, not implemented: cannot expand inline function
		       needing temporary variable of vector type

This problem disappears when Foo:doit () is changed to a non-inline function.
I'd like to know if this is a bug, a feature or a limitation with our current
version of cfront (or if there's something wrong with my code).  Thanks in
advance!
