My hypothesis is based on the experiment on the trivial helloworld.c with
gcc and g++. While gcc compiles and links with the
-Wno-non-literal-null-conversion argument, g++ doesn't.

My hypothesis for the fail step is that cc1plus is invoked in the
background which bonks with this argument. I will google to see if that's
the behavior in mixed (C and C++) codebases.

So adding actual code to be compiled doesn't make any difference, it still

Of course, we can drop this argument as a workaround. Barring that,
configure is setting CFLAGS and CXXFLAGS correctly.  Rats indeed!
