# If we leave MAKEFLAGS set, then it's fair game to complain that the

# advertised file descriptors are gone, because GNU make also complains.

# (Although they only warn while we abort. They can't abort so that
|
||
|
|
# they don't break backward compat, but we have no such constraint, because

# redo has always failed for that case.)

# redo should recover silently from that problem.
