// This file tests that we correctly deal with weak undefined symbols
// when searching archive libraries. If we have a weak undefined symbol,
// it should not cause us to link an archive library member that defines
// that symbol. However, if the symbol is also listed in a -u option on
// the command line, it should cause the archive member to be linked.
