Add the LAST_ARG_MUST_BE_NULL macro
The sentinel function attribute is not understood by versions of the gcc compiler prior to v4.0. At present, for earlier versions of gcc, the build issues 108 warnings related to the unknown attribute. In order to suppress the warnings, we conditionally define the LAST_ARG_MUST_BE_NULL macro to provide the sentinel attribute for gcc v4.0 and newer.
