     This merely indicates that there already is a constant defined 
externally in some xxx.h or xxx.c of that name. All it does is define a 
Sather name so that the Sather compiler can put in the relevant linking 
information for gcc - with 'external class' name mangling, rather than 
ordinary Sather class name mangling.
