I asked Nelson to try compiling hello on his array of systems, which he
graciously did. It basically went fine, and then he went further and tried
compiling it with C++ compilers. The hello code itself is so simple it
is no problem, but there are a variety of syntax errors in various
gnulib modules with C++, included below.
Is supporting compilation with C++ of interest? (I'm not arguing for
it, just reporting it, since Nelson went to the trouble of trying it.)
Best,
Karl

Here is a sprinkling of the kinds of errors C++ compilers reported
about hello-2.1.94 on just one mchine; I suspect all of them are
trivial to fix:
