This uses the gnu11 standard, which is C11 with GNU extensions. Previously, gnu89 was being used, which is pretty ancient by now. C99 brings some important improvements, some of which were already available and used even without this option. C11 is more recent and brings more minor improvements. Most notable feature is the static_assert statement, allowing checking invariants at compiletime using the full C expressions.
