689 The old way called symtab_finalize before the is_static pass,
690 causing a problem since symtab_finalize uses is_static as part of
691 its address conflict resolution algorithm. Since global symbols
692 were prefered over static symbols, and all line symbols were
693 global at that point, static function names that conflicted with
694 their own line numbers (static, but labeled as global) were
695 rejected in favor of the line num.
696
697 This was not the desired functionality. We always want to keep
698 our function symbols and discard any conflicting line symbols.
699 Perhaps symtab_finalize should be modified to make this
700 distinction as well, but the current fix works and the code is a
701 lot cleaner now. */
