Options
- 1To make variables implicitly thread-local so each thread gets its own instance
- 2To allow multiple definitions of the same variable across TUs with one shared entity
- 3To force dynamic initialization of the variable before main runs in every TU
- 4To allow variables of incomplete type to be defined in more than one TU at once
