* gdb/objc-lang.c (objc_printstr): Add width arg to match
printstr prototype. (compare_selectors): Add 'const' to arg types. (compare_classes): Likewise. (find_imps): Cast msym pointer to avoid compiler warning. (print_object_command): Validate the address before passing it to the print routine. (find_objc_msgcall_submethod): Change function argument to return an int. * objc-lang.h: Add 'extern' to all function declaration. (value_nsstring): Add declaration.
