# There is no correct way to write a rule that generates two files.
# Rules with two targets don't have that meaning, they are merely
# shorthand for two otherwise separate rules.  If we have an action
# that in fact generates two or more files, we must choose one of them
# as primary and show it as the action's output, then make all of the
# other output files dependent on the primary, like this.  Furthermore,
# the "touch" action is essential, because it ensures that gram.h is
# marked as newer than (or at least no older than) gram.c.  Without that,
# make is likely to try to rebuild gram.h in subsequent runs, which causes
# failures in VPATH builds from tarballs.
