  51 # See comments in build-aux/git-version-gen.  However, we make .version depend
  52 # on configure so that .version and VERSION/PACKAGE_VERSION stay in sync in the
  53 # working copy (for example, when you run autoreconf && make).  Allowing these
  54 # to fall out of sync appears to have little potential to improve Bison build
  55 # efficiency (even if we were to replace VERSION/PACKAGE_VERSION with .version
  56 # everywhere possible).  On the other hand, it could be harmful.  For example,
  57 # a developer might naively reference .version in a test case while the bison
  58 # executable still compiles with VERSION, and so the test case might fail or
  59 # pass incorrectly.
