AX_CXX_HELPFUL_TERMINATE_HANDLER: initial version
Submitted by Kevin Locke in <https://savannah.nongnu.org/patch/index.php?7005>:
| As a compliment (or possibly replacement) to the current
| AX_CXX_VERBOSE_TERMINATE_HANDLER macro, I present the
| AX_CXX_HELPFUL_TERMINATE_HANDLER macro. Rather than specifically looking for
| the GNU libstdc++ verbose_terminate_handler, this macro uses a test program
| which throws an uncaught exception then checks if the output contains
| information about the exception. This way it can detect helpful terminate
| handlers other than the current one provided with GNU libstdc++.
|
| The design of this macro is not perfect. Most importantly, the logic for
| capturing and testing the output of the test program is not very elegant. I
| had first attempted to check for output from within the test program (by
| redirecting std::cerr, capturing SIGABRT, etc.) but it was excessively ugly
| and not very portable. The result is that the logic in the macro itself is a
| little more awkward so that the test program is trivial. I think it was a
| good trade, but feedback is welcome.
