Bison is written using Bison grammars, so there are bootstrapping
issues. The bootstrap script attempts to discover when the C code
reveal if the current version of the submodule (i.e., the actual
contents of the gnulib directory) and the current request from the
subscriber (i.e., the reference of the version of gnulib that the
-Bison reporitory requests) differ. To upgrade the submodules (i.e.,
+Bison repository requests) differ. To upgrade the submodules (i.e.,
to check out the version that is actually requested by the subscriber,
run "git submodule update".

-The autoconf files we use are currently:
+The Autoconf files we use are currently:
m4/m4.m4
lib/m4sugar/m4sugar.m4
** make check
Use liberally.
+** make maintainer-check-valgrind
+This target uses valgrind both to check bison, and the generated parsers.
+
+This is not mature on Mac OS X. First, Valgrind does support the way bison
+calls m4, so Valgrind cannot be used to check bison on Mac OS X.
+
+Second, there are many errors that come from the platform itself, not from
+bison. build-aux/darwin11.4.0.valgrind addresses some of them.
+
+Third, valgrind issues warnings such as:
+
+ --99312:0:syswrap- WARNING: Ignoring sigreturn( ..., UC_RESET_ALT_STACK );
+
+which cause the test to fail uselessly. It is hard to ignore these errors
+with a major overhaul of the way instrumentation is performed in the test
+suite. So currently, do not try to run valgrind on Mac OS X.
+
** Release checks
Try to run the test suite with more severe conditions before a
release:
Push these changes.
