Start of TAGGED_ARRAY() infrastructure.
This lets you have struct arrays with a string as the first member, ala:
struct {char *name; int x, y} blah thingy[] = TAGGED_ARRAY(BLAH,
{"one", 1, 2}, {"two", 3, 4}, {"three", 5, 6}
);
And it produces #defines for the array index of each, ala:
#define BLAH_one 0
#define BLAH_two 1
#define BLAH_three 2
So you can use thingy[BLAH_two].x and still reorder the elements at will.
Note: if you screw up the array initializers, temporarily replace
TAGGED_ARRAY(BLAH, with { and the ); with }; and the compiler will give you
better error messages. (With the macro the compiler reports errors on the
TAGGED_ARRAY line, not where the comma is missing in its contents.)
Currently the TAGGED_ARRAY( and ); must be on their own lines, and the
{ and start of each attached string must be on the same line.
