  61 # Some of our targets (cross-option.texi, bison.1) use "bison --help".
  62 # Since we want to ship the generated file to avoid additional
  63 # requirements over the user environment, we used not depend on
  64 # src/bison itself, but on src/getargs.c and other files.  Yet, we
  65 # need "bison --help" to work to make help2man happy, so we used to
  66 # include "make src/bison" in the commands.  Then we may have a
  67 # problem with concurrent builds, since one make might be aiming one
  68 # of its jobs at compiling src/bison, and another job at generating
  69 # the man page.  If the latter is faster than the former, then we have
  70 # two makes that concurrently try to compile src/bison.  Doomed to
  71 # failure.
  72 #
  73 # As a simple scheme to get our way out, make a stamp file,
  74 # bison.help, which contains --version then --help.  This file can
  75 # depend on bison, which ensures its correctness.  But update it
  76 # *only* if needed (content changes).  This way, we avoid useless
  77 # compilations of cross-option.texi and bison.1.  At the cost of
  78 # repeated builds of bison.help.
