My bad. The entire struct is defined as static.
The static identifier was to prevent external modifcation of the value.
However since it's encased in a "static struct local" it's not an issue.
True. Any initialized value needs to be shipped into .data, and we
begin to see some ugly .data bloat (even if the user is just specifying
zero anyway...)
I think I'm going to get some sleep now ... to many "my bad" in one
day ^__^;;;
