-# Until 2020-09-25, the very last dependency group of a top-level makefile
-# was not finished properly.  This made it possible to add further commands
-# to that target.
-#
-# In pass 1, there is a dependency group at the bottom of the file.
-# This dependency group is not finished properly.  Finishing the dependency
-# group would add the OP_HAS_COMMANDS flag to the "all" target, thereby
-# preventing any commands from being added later.
-#
-# After the file has been parsed completely, it is parsed again in pass 2.
-# In this pass, another command is added to the "current dependency group",
-# which was still the one from pass 1, which means it was possible to later
-# add commands to an existing target, even across file boundaries.
-#
-# Oops, even worse.  Running this test in a make from 2020-09-25 or earlier
-# on NetBSD 8.0 x86_64 with MALLOC_OPTIONS=JA produces this or a similar
-# output:
-#
-#      make: cannot open ZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZ.
-#
-# The 'Z' means access to already freed memory; see jemalloc(3).  The cause
-# for this is that in MainParseArgs, the command line arguments were not
-# properly copied before storing them in global variables.
