Ralf W. Grosse-Kunstleve af7007331a Removing GCC -Wunused-but-set-parameter from pragma block at the top of pybind11.h (#3164) ... * Cleanup triggered by work on pragma for GCC -Wunused-but-set-parameter. * Backing out changes to eigen.h (to be worked on later). * Adding PYBIND11_WORKAROUND_INCORRECT_GCC_UNUSED_BUT_SET_PARAMETER in type_caster_base.h (apparently needed only for older GCCs). * Apparently older compilers need a simpler overload for silence_unused_warnings(). * clang C++11 compatibility: removing constexpr * Special case for MSVC 2017: `constexpr void` return * Trying again without the silence_unused_warnings(const int *) overload. * Separate macros for ALL_GCC, OLD_GCC_UNUSED_BUT_SET_PARAMETER * Changing to __GNUC__ <= 2 (turning off) * Refined condition for PYBIND11_WORKAROUND_INCORRECT_OLD_GCC_UNUSED_BUT_SET_PARAMETER. * Quick experiment trying out suggestion by @henryiii * Introducing macro: PYBIND11_INT_ARRAY_WORKING_AROUND_MSVC_CLANG_ISSUES * Trying henryiii@ (void) expander idea. * fix: apply simpler expression with fewer workarounds * Purging new-but-already-obsoleted macro, made possible by @henryiii's commit. * Renaming `ALL_GCC` macro back to just `GCC` (because there is no `OLD` anymore, luckily). * [actions skip] Adding "All GCC versions" to comment, to be clear about it.
