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