Sure: make the variable non-static and import it into your dissector. 
(This assumes you can/don't mind modifying the other dissectors.)  For 
example, the "mtp3_standard" preference variable is used by quite a few 
different dissectors.

(Also: this might not work--at least easily--if you're doing it in a 
plugin on Windows.)
