c++tools, configury: Configure with C++; test checking status [PR98821].
The c++tools configure fragments need to be built with a C++ compiler.
In addition, the stand-alone server uses diagnostic mechanisms in common
with GCC, but needs to define implementations for gcc_assert and
supporting output functions.

c++tools/ChangeLog:
* config.h.in: Regenerate.
* configure: Regenerate.
* configure.ac: Configure using C++. Pull logic to
detect enabled checking modes; default to release
checking.
* server.cc (AI_NUMERICSERV): Define a fallback value.
(gcc_assert): New.
(gcc_unreachable): New.
(fancy_abort): Only build when checking is enabled.
