Yes, that's the jist of it. > Don't think I can change the bug topic. > Is that a known issue with an already open bug? > I don't know of one, but this is probably sufficient. I can't think of a valid situation where someone would want leading/trailing whitespace as part of a variable name, so it's probably safe to just call strip( gmk_expand( argv[0] ) ) in $(foreach) and have done with it. It would still allow the temporary variable to use whitespace between non-whitespace characters, and that seems like the most obscure case that should be supported. -brian
