# Test detailed error handling in compat mode.
#
# Until 2020-12-13, .ERROR_TARGET was success3, which was wrong.
# Since compat.c 1.215 from 2020-12-13, it is 'fail1', which is the first
# failed top-level target.  XXX: Even better would be if .ERROR_TARGET were
# the smallest target that caused the build to fail, even if it were a
# sub-sub-sub-dependency of a top-level target.
#
# XXX: As of 2020-12-13, .ERROR_CMD is empty, which is wrong.
