[gcjx] Patch: FYI: fix parser bug with types

[Tom Tromey <tromey at redhat dot com>]

I'm checking this in on the gcjx branch.

This fixes a small parser bug with generic types.  We were looking for
'[]' even when closing multiple generic types at once.  This is a test
case:

    class gen<T> { }
    class gen2<T> { }

    class base {
      public gen<?>[] m() { return null; }
    }

    public class overr2 extends base {
      public gen<gen2<String>>[] m() { return null; }
    }

	* source/parse.cc (counted_type): Don't look for [] if multiple
	<> were closed at once.
