# Source code generated by bison 2.6.4 contains pragmas that trigger
# warnings when built with -Wunknown-pragmas. Since Grub compiles with
# -Werror, this causes the build to fail. We work around this issue by
# ignoring pragma-related warnings, but clearly it would be better if
# Bison wouldn't trigger that issue in the first place. A bug report
# has been sent.
