I Checked out the latest 21-2 from CVS Saturday evening and built it under Cygwin 20.1. I ran the automated tests with "make check" and saw an error on the database test as shown in the excerpt below. The remaining tests were successful. Testing /develop/xemacs/tests/automated/database-tests.el... Unexpected error (wrong-type-argument databasep nil) while executing interpreted code. Test suite execution aborted. Unexpected error (wrong-type-argument databasep nil) while executing byte-compiled code. Test suite execution aborted. database-tests.el: 0 of 2 (0%) tests successful. Test suite execution failed unexpectedly.
