make/tests/scripts/features/load
Paul Smith e33f3d72bf [SV 46581] Pre-define .LOADED to avoid warnings.
* main.c (main): Pre-define .LOADED as a default-level variable.
* load.c (load_file): Set the value rather than append it.  Avoid
adding an extra initial whitespace.
* tests/scripts/features/load: Run with --warn-undefined-variables.
