Oops, wrong git commit message.  Here is the correct one (fixed before
pushing)
:

    tests: avoid failure due to libtool quirks in C++ demo test

    Revealed by failures on NetBSD 5.1.

    * t/cxx-lt-demo.sh: In "make distcheck" invocation, don't define 'CC'
    to "false", as that value would be exported and passed to the child
    ./configure invocation, and some configure checks generated by libtool
    autoconf macros can still require a C preprocessor even for packages
    using only C++, and bail out if it's not found.  The problem was not
    apparent on Solaris and GNU/Linux because those systems have a
    '/lib/cpp' program, and configure detected and used that as a fallback
    C preprocessor.

Sorry for the noise,
