gpgme/m4/ax_cxx_compile_stdcxx.m4, branch gpgme-1.24.1

build: Update ax_cxx_compile_stdcxx macro

2022-08-22T13:04:32Z

* m4/ax_cxx_compile_stdcxx.m4: Replace with current version from the autoconf archive. -- This fixes the problem that the switch -std=c++11 was omitted if the compiler supported C++11 features by default. This made gcc happily compile C++14 code. Now C++11 is enforced by gcc. GnuPG-bug-id: 6141

Cpp: Set -std=c++11 also if CXXCPP is already set

* m4/ax_cxx_compile_stdxx.m4 (AX_CXX_COMPILE_STDCXX): Set CXXCPP if neccessary. -- This fixes the build with scan-build where CXXCPP is already set but does not include stdc++11. While this deviates from the autotools-archive version of the script it does not make sense to me first to check if stdc++11 needs to be set and then not set it.

Cpp: Require c++ 11 if cpp binding requested

* configure.ac: Call ax_cxx_compile_stdcxx * m4/ax_cxx_compile_stdcxx.m4 -- Depending on c++11 is intended to make the port away from Boost easier. The m4 macro was taken from the website mentioned in the License header of the file.
