# -------------------------------------------------
-# Check Bison by invoking `bison BISON_ARGS'. OTHER_AT_CHECK_ARGS are the
-# usual remaining arguments to AT_CHECK: STATUS, STDOUT, etc.
+# Check Bison by invoking `bison BISON_ARGS'. BISON_ARGS should not contain
+# shell constructs (such as redirection or pipes) that would prevent
+# appending additional command-line arguments for bison. OTHER_AT_CHECK_ARGS
+# are the usual remaining arguments to AT_CHECK: STATUS, STDOUT, etc.
#
# This macro or AT_BISON_CHECK_NO_XML should always be used whenever invoking
# Bison in the test suite. For now it ensures that:
#
# 3. If stderr contains a warning, -Werror and --warnings=error
# convert the warning to an error.
+#
+# 4. If stderr contains a warning, -Wnone and --warnings=none suppress it.
