Building with C++20 and the following error is triggered

[Smurf-IV]

I have Level 4 and warnings as errors turned on as part of the code standard we use...

This results in the following being triggered:

1>Z:\Repos\SRLE\Thirdparty\PoC\toml11\include\toml\exception.hpp(18,66): error C4996: 'strerror': This function or variable may be unsafe. Consider using strerror_s instead. To disable deprecation, use _CRT_SECURE_NO_WARNINGS. See online help for details.

Fixed.

Since strerror_s is only available in MSVC (actually it is not a part of C++), it uses strerror_s only when it is compiled using MSVC and uses strerror_r on linux.

Anyway, since the only function that may call strerror is the FILE* version of the toml::parse, so in most cases people would not be affected by this.
