# Some of our targets (cross-option.texi, bison.1) use "bison --help".
# Since we want to ship the generated file to avoid additional
# requirements over the user environment, we used not depend on
# src/bison itself, but on src/getargs.c and other files.  Yet, we
# need "bison --help" to work to make help2man happy, so we used to
# include "make src/bison" in the commands.  Then we may have a
# problem with concurrent builds, since one make might be aiming one
# of its jobs at compiling src/bison, and another job at generating
# the man page.  If the latter is faster than the former, then we have
# two makes that concurrently try to compile src/bison.  Doomed to
# failure.
#
# As a simple scheme to get our way out, make a stamp file,
# bison.help, which contains --version then --help.  This file can
# depend on bison, which ensures its correctness.  But update it
# *only* if needed (content changes).  This way, we avoid useless
# compilations of cross-option.texi and bison.1.  At the cost of
# repeated builds of bison.help.
