`false` not currently working for Windows and Ubuntu platforms

[sbearrows]

Currently false is not working for certain versions of Windows and all versions of Ubuntu on R CMD check

Might need a new template specialization for initializer_list<bool>

cpp11/inst/include/cpp11/logicals.hpp

Lines 76 to 84 in fe9850f

	template <>
	inline r_vector<r_bool>::r_vector(std::initializer_list<r_bool> il)
	: cpp11::r_vector<r_bool>(Rf_allocVector(LGLSXP, il.size())), capacity_(il.size()) {
	protect_ = preserved.insert(data_);
	auto it = il.begin();
	for (R_xlen_t i = 0; i < capacity_; ++i, ++it) {
	SET_LOGICAL_ELT(data_, i, *it);
	}
	}
