Hitting error while compiling on windows:

error C3861: 'unsetenv': identifier not found

Reason: unsetenv() is a POSIX function; it doesn’t exist on Windows. Visual Studio (MSVC) won’t recognize it.

Proposed fix: Use _putenv_s() (Windows equivalent)
This is supported by MSVC and achieves the same effect: it removes the environment variable from the process environment.

This keeps cross-platform compatibility.
