Some of our targets use "bison --help", but they can't depend on "bison" itself (to avoid additional requirements on the user), so they used to call "make src/bison" in the commands. Then concurrent builds may fail: 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. This might also be a more convincing explanation for the failure described in the patch "build: fix paths". * Makefile.am (SUFFIXES): Initialize. * build-aux/move-if-change: New, symlink to gnulib's. * build-aux/local.mk: Ship it. * doc/common.x: Remove, merged into... * doc/bison.x: here. * doc/local.mk (doc/bison.help): New. ($(CROSS_OPTIONS_TEXI)): Depend on it. Use src/bison. (.x.1): Replace with... (doc/bison.1): this explicit, simpler, target. (common_dep): Remove, inlined where appropriate. (SUFFIXES, PREPATH): Remove, unused.

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