Hello Bogdan,

$ c++ --version
OpenBSD clang version 13.0.0
Target: amd64-unknown-openbsd7.4
Thread model: posix
InstalledDir: /usr/bin

Yes, 'c++' works as an Objective-C++ compiler:
================================= hello.mm ==========================
#import <stdio.h>
#import <stdlib.h>
#import <iostream>

class X { int a; };

int main(void)
{
    @autoreleasepool
    {
        std::cout << @"Hello, Objective-C++.";
    }
    
    return EXIT_SUCCESS;
}
======================================================================
$ c++ -c hello.mm
$ c++ hello.mm
[3 link errors, due to undefined symbols.]

>   What Autoconf version do your have and can you upgrade that?

I was testing automake-1.16j.

Find attached the config.log.
