 # Since we want to ship the generated file to avoid additional

 # 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-options.texi and bison.1.  At the cost of
