* src/load.c (load_file): Update .LOADED if setup returns non-0. * tests/scripts/features/load: Change the return value based on an environment variable. Ensure that returning -1 still adds to .LOADED. Also add a test that verifies that make doesn't try to rebuild the loaded file if -1 is returned.
