#define BOOST_DISABLE_ASSERTS

// This prevents spirit grammar rules from generating a very large and/or deep
// call-graph where rules compose together using wrapped indirect calls through
// boost::function -- this is higly inefficient as the grammar's logic ends up
// being a fraction of the generated code and the rest is invocation related
// overhead. By force-flattening here we can allow each entry-point into
// spirit to compose rules at once and eliminate the wrapping complex.
