Original author here: No, we use 'C' and 'C++' on Windows PCs, and we use 'C' and 'C++' and 'Objective C' on the Macintosh. Objective C can call into 'C' libraries just fine on the Macintosh. Objective C can also call into C++ just fine on the Macintosh. The distinctions are very important to us. :-) Objective C cannot compile on Linux or Windows, but 'C' and 'C++' can compile on all three platforms (Macintosh, Linux, and Windows) using the default development environments on all three platforms (GCC on Linux, Xcode on Macintosh, Visual Studio on Windows).
