Renderer configuration outputs false warnings in MSVC compiled execs

Reading renderer configuration files with UNIX style endings and IVAS compiled in MSVC will generate false warnings. The error could be severe, since there is a bug in the ftell() function for text files with UNIX style endings, see https://developercommunity.visualstudio.com/t/fseek-ftell-fail-in-text-mode-for-unix-style-text/425878

The same link suggests a workaround to handle this issue.
