* you do
* DECL_STRINGS_4(static, foo, "alpha", "beta", "gamma", "delta");
*
* and it comes out as
* static char foo_0[] = "delta";
* static char foo_1[] = "gamma";
* static char foo_2[] = "beta";
* static char foo_3[] = "alpha";
* static char *foo[4] = { foo_3, foo_2, foo_1, foo_0 };
*
* none of which is const.
*
* Unfortunately, the string arrays this program slings around freely
* can't be all const (because it munges some of them) and can't be
* all non-const without something like this to initialize the ones
* that need to contain string constants. Unfortunately you can't
* mix (const char *const *) and (char **) in C, only in C++.
