** FILE ** Former Senegalese President Leopold Sedar Senghor is seen in Verson, France in this Oct. 1996 file photo. Five years after his death at age 95, Senghor remains an icon _ a key figure in helping Senegal gain independence and then the first postcolonial African leader to step down voluntarily in 1980. Celebrations for the 100th anniversary of his birth are occurring not just in his home country but also across the world _ from the French Carribean island of Martinique to Canada.
