Hi,
This attempts to clean up and update these
sigc++config.h.*
files a bit in regards to Visual Studio:noexcept
, since we require Visual Studio 2017 or later for libsigc++-3.x.warning C4251
in the comments still applies today, and attempting to try to see whether we can exportstd::list
can risk breaking ABI, so update the comment there.Do we still have any libsigc++-2.x versions beyond 2.12? If so, I think we could just drop VS2013 support, since the latest C++11 releases of items that use libsigc++-2.x would actually require VS2015 (or even VS2017 for libxml++-3.x) or later.
With blessings, thank you!
