# Test whether OP_SUBMAKE is determined correctly. If it is, this node's
# shell commands are connected to the make process via pipes, to coordinate
# the number of running jobs.
#
# Determining whether a node is a sub-make node happens when the node is
# parsed. This information is only used in parallel mode, but the result
# from parsing is available in compat mode as well.
