This has been a soft requirement since 1.5.0; anyone on such platforms would have had to configure --without-64-bit, provoking a warning that instructed them to report a D-Bus bug with details of their platform. Nobody has done so, so if anyone still lacks a 64-bit integer type, they're on their own. (Also, I tried the build with --without-64-bit and it's full of fatal compiler warnings, so it's not clear that we're actually losing anything by removing this "feature".)
