   3 # Test detailed error handling in compat mode.
   4 #
   5 # Until 2020-12-13, .ERROR_TARGET was success3, which was wrong.
   6 # Since compat.c 1.215 from 2020-12-13, it is 'fail1', which is the first
   7 # failed top-level target.  XXX: Even better would be if .ERROR_TARGET were
   8 # the smallest target that caused the build to fail, even if it were a
   9 # sub-sub-sub-dependency of a top-level target.
  10 #
  11 # XXX: As of 2020-12-13, .ERROR_CMD is empty, which is wrong.
