* @file: nana/config.hpp
* @file nana/config.hpp
*
* @brief Provide switches to adapt to the target OS, use of external libraries or workarounds compiler errors or lack of std C++ support.
*
* To control target OS/compiler:
* - NANA_WINDOWS
* - NANA_MINGW
* - NANA_POSIX
* - NANA_LINUX
* - NANA_MACOS
* - NANA_X11
* - NANA_UNICODE
*
* External libraries:
* - NANA_LIBPNG, USE_LIBPNG_FROM_OS
* - NANA_LIBJPEG, USE_LIBJPEG_FROM_OS
*
* (see: Feature-testing recommendations for C++
* in http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2015/p0096r0.html
* for example: __cpp_lib_experimental_filesystem = 201406 in <experimental/filesystem)
*
* Workaround to known compiler errors, unnecessary warnings or lack of C++11/14/17 support:
* - _SCL_SECURE_NO_WARNNGS, _CRT_SECURE_NO_DEPRECATE (VC)
* - STD_CODECVT_NOT_SUPPORTED (VC RC, <codecvt> is a known issue on libstdc++, it works on libc++)
* - STD_THREAD_NOT_SUPPORTED (GCC < 4.8.1)
* - STD_NUMERIC_CONVERSIONS_NOT_SUPPORTED (MinGW with GCC < 4.8.1)
* - USE_github_com_meganz_mingw_std_threads (MinGW with GCC < 4.8.1)
* - STD_NUMERIC_CONVERSIONS_NOT_SUPPORTED (MinGW with GCC < 4.8.1)
* - STD_TO_STRING_NOT_SUPPORTED (MinGW with GCC < 4.8)
* - STD_make_unique_NOT_SUPPORTED (MinGW with GCC < 4.8.1)
* or __cpp_lib_make_unique
