There's three options, at least for a POD variable that doesn't incur an 
atexit destructor:

* In environments where HAVE_THREADSAFE_STATICS (config_global.h) is 
guaranteed to be 1, just use a plain static variable.

* Otherwise, use the rtl/instance.hxx machinery.

* Or, for code in the sal library, add any necessary initialization to 
sal_detail_initialize.
