+ * nm.c (struct extended_symbol_info): New strcuture: Add the size
+ of the symbols to the information provided by the symbol_info
+ structure.
+ (print_symbols): Pass the symbol size to print_symbol.
+ (print_size_symbols): Pass the symbol size to print_symbol.
+ (print_symbol): Extra argument: The size of the symbol. Store
+ this in the extended_symbol_info structure.
+ (print_symbol_info): Change type of info parameter to
+ extended_symbol_info. Display the size, if known.
+ (print_symbol_info_posix): Likewise.
+ (print_symbol_info_sysv): Likewise.
+
