[Cpp Runtime] MSVC: ANTLRFileStream uses removed "s2ws"

[enricop]

Hello,

master branch of runtime cpp fails to compile with MSVC on the following line:

thanks for your support,

[jcking]

I believe this should be resolved in 4.10.

Hello, thank you for the reply. Looking forward for the release.

@jcking Release 4.10 still fails to compile. Runtime source does not provide any definition for antlrcpp::s2ws:

antlr4-cpp-runtime\ANTLRFileStream.cpp(17): error C2653: 'antlrcpp': is not a class or namespace name
antlr4-cpp-runtime\ANTLRFileStream.cpp(17): error C3861: 's2ws': identifier not found

From my attempt to upgrade to 4.10: https://github.com/SystemRDL/systemrdl-compiler/runs/6001839774

Grepping the contents of runtime shows this is missing:

$ grep -r s2ws antlr4-cpp-runtime-4.10-source/
antlr4-cpp-runtime-4.10-source/runtime/src/ANTLRFileStream.cpp:  std::ifstream stream(antlrcpp::s2ws(fileName), std::ios::binary);
antlr4-cpp-runtime-4.10-source/demo/Windows/antlr4-cpp-demo/main.cpp:  std::wstring s = antlrcpp::s2ws(tree->toStringTree(&parser)) + L"\n";

as does searching the contents of the antlr repository: https://github.com/antlr/antlr4/search?q=s2ws
