Oops, I forgot the key is to have AC_PROG_CXX and AC_PROG_CXXCPP
expanded, but only executed when desired.  The dead hand of AC_REQUIRE
I suspect :-).

Actual example below.  No c++ probes,

        ./configure

unless enabled,

        ./configure --enable-cxx

As I say, dunno if this is the right way, but it gets something like
the right effect.
