Some experimentation says that this is a mismatch between the default C++
version for the host/installed gcc (for me, C++11, I think) and the target
(C++17, right?).  If you add "-std=c++17" to the invocation line in gcc.log,
compilation succeeds.  Or, change the form of the newly introduced declarations
from
 auto foobar = foo<bar>();
to
 foo<bar> foobar;
Not sure why the former is used, it seems negate the benefits of auto and just
be more typing.  Beware: since I know Very Little C++ of the last decades, I
could be completely wrong.
