Use "#pragma once" as include guard
While "#pragma once" is not part of the C or C++ standards, it is a construct
supported "by the vast majority of modern compilers"[1]. The previously used
include guards starting with two underscores were also in violation of the
relevant standards: identifiers starting with a double underscore ("__") are
reserved for the implementation[2].
