**
** This file contains macros for building Actor defaults lists
** Defaults lists are byte-packed arrays of keys and values.
**
** For Visual C++, a simple byte array will do, with one
** restriction: Any strings must be at the end of the array.
**
** For GCC, we need to get more complicated: Everything needs
** to be a separate variable. Fortunately, GCC byte-aligns
** char variables, so as long they appear in the right order
** (which they do in all version I tried), this will work.
