Unfortunately C++ is not standardized. Not even the filename extension is standardized: some projects use .cc, some use .cpp, some use .cxx, some use .c++, and some use .C (capital C) which is obviously bad since the filesystem might be case-insensitive, but I've seen it done. There are likely others. This makes it difficult to write a default rule to compile C++ source files and I'm not excited about creating separate rules for all the above extensions. > As of POSIX 2024, make defaults the C standard version to C17.

There is already a default variable CXX in GNU Make holding the name of the C++ compiler, and has been for 32 years. So we don't need to worry about that. If you're asking that the CXX variable be defined in POSIX, you'll have to ask the committee about that. -- Paul D.
