# Tests for the special target .IGNORE in dependency declarations, which
# does not stop if a command from this target exits with a non-zero status.
#
# This test only applies to compatibility mode.  In jobs mode such as with
# '-j1', all commands for a single target are bundled into a single shell
# program, which is a different implementation technique, the .IGNORE applies
# there as well.
