Fixes compilation issue #403 and improves error reporting

[mikucionisaau]

Fixes #403 , similar to pr #423 but improved error reporting (e.g. #408).
Tested on g++-10/11/12/13/14, clang++-16, mingw-g++-13 (Debian testing)

The error reporting is better:

• backward compatible (std::system_error inherits std::runtime_error, so catch(std::runtime_error&) works as before).
• uses C++ standard exceptions.
• uses platform specific error messages (for example "filepath: File not found" on Windows and "filepath: No such file or directory" on Linux).
• includes the details like a filepath or a function name.

Looks good to me. It needs to be rebased, though.
