-Put uninitialized or run-time-initialized global variables into the
-common segment, as C does. This saves space in the executable at the
-cost of not diagnosing duplicate definitions. If you compile with this
-flag and your program mysteriously crashes after @code{main()} has
-completed, you may have an object that is being destroyed twice because
-two definitions are merged.

-This option is no longer useful on most targets, now that support has
-been added for putting variables into BSS without making them common.
