From 2468253c9adbb1e42be9227848c2d9a7b578dbaf Mon Sep 17 00:00:00 2001 From: Antonio Sanchez Date: Mon, 1 Mar 2021 15:57:22 -0800 Subject: Define EIGEN_CPLUSPLUS and replace most __cplusplus checks. The macro `__cplusplus` is not defined correctly in MSVC unless building with the the `/Zc:__cplusplus` flag. Instead, it defines `_MSVC_LANG` to the specified c++ standard version number. Here we introduce `EIGEN_CPLUSPLUS` which will contain the c++ version number both for MSVC and otherwise. This simplifies checks for supported features. Also replaced most instances of standard version checking via `__cplusplus` with the existing `EIGEN_COMP_CXXVER` macro for better clarity.
