Subject: [PATCH]         * som.c (bfd_section_from_som_symbol): Renamed from  
       som_section_from_subspace_index.  Pass in a native SOM symbol.        
 For executables, iterate through the sections to find out         which
 contains the symbol's address rather than using the         symbol_info
 field.  (symbol_info has a different meaning for         dynamicly linked
 executables.)
