# Tests for the -k command line option, which stops building a target as soon
# as an error is detected, but continues building the other, independent
# targets, as far as possible.
#
# Until 2020-12-07, if a dependency of the main target failed, the exit
# status was nevertheless 0, which was wrong since the main targets could
# not be made.  This was only wrong in -k mode combined with compat mode.
