Q: __func__ in msvc

[masatake]

@k-takata I have a question about msvc.

During making a pull request, I found msvc didn't know __func__.
__func__ is part of C99.

__func__ is so useful for debugging and making useful error messages.
Don't you know any alternative to __func__ in msvc?

As far as reading
https://learn.microsoft.com/ja-jp/cpp/preprocessor/predefined-macros?view=msvc-140,
__func__ is available. Do we use older msvc?

[k-takata]

Currently, we support VC++ 2013 or later, and I think we use it on AppVeyor.
VC++ 2015 has better support for C99. I think we can drop support for 2013.

MSVC has __FUNCTION__.

Thank you!

I think we can drop support for 2013.

I will reopen this when 2023:-)
