* Factor out pybind11/compat/wrap_include_python_h.h * Fixes to resolve tests_packaging failures. * Factor out pybind11/compat/pybind11_platform_abi_id.h * Add pybind11/compat/README.txt and a couple source code comments. * Minor changes to comments. * Factor out pybind11/compat/pybind11_conduit_v1.h * Add long comment to pybind11/compat/pybind11_conduit_v1.h * Add pybind11/compat/README.txt to wheels. * Add `-fno-exceptions` to compiler options for exo_planet_c_api * 1. Move `target_compile_options()` into loop over test targets, in case the `"exo_planet_c_api"` target does not exist. 2. Add `-fno-exceptions` option also for `NVHPC`. 3. Also check for `__cpp_exceptions` in exo_planet_c_api.cpp. * 1. Fix accident (forgot to undo temporary change). 2. Special-case __EMSCRIPTEN__ in exo_planet_c_api.cpp * Give up on compiling exo_planet_c_api.cpp with MSVC `/EHs-c-`: There was one trouble maker (all other jobs worked): Visual Studio 15 2017: ``` cl : Command line warning D9025: overriding '/EHc' with '/EHc-' [C:\projects\pybind11\tests\exo_planet_c_api.vcxproj] ... C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\VC\Tools\MSVC\14.16.27023\include\xlocale(319): error C2220: warning treated as error - no 'object' file generated [C:\projects\pybind11\tests\exo_planet_c_api.vcxproj] C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\VC\Tools\MSVC\14.16.27023\include\xlocale(319): warning C4530: C++ exception handler used, but unwind semantics are not enabled. Specify /EHsc ``` * Move pybind11/compat to pybind11/conduit as suggested by @henryiii: https://github.com/pybind/pybind11/pull/5375#pullrequestreview-2329006001
