commit    3d28ecb5ac76ae29ca0837dc81e7dacc2ab215eb
Author:   Peter Eisentraut <peter@eisentraut.org>

    Test List macros in C++ extensions
    
    All of these macros already work in C++ with Clang and GCC (the only
    compilers we're currently testing C++ extension support for).  This
    adds a regression test for them in our test C++ extension, so we can
    safely change their implementation without accidentally breaking C++.
    Some of the List macros didn't work in C++ in the past (see commit
    d5ca15ee5), and this would have caught that.
