+   here, (currently at least) means a BFD section, and the sections
+   are set up from the BFD sections in allocate_objfile.
+
+   The sections in section_offsets have their meaning determined by
+   the symbol format, and they are set up by the sym_offsets function
+   for that symbol file format.
