Clang 9 (in Visual Studio) complains about a mixed signed-unsigned comparison and an unused function. Replace the naked `int` constant -1 by `std::size_t(-1)` with the same codegen as before (no curlies to avoid narrowing). Guard the definition of `get_download_folder()` by the same condition as its call-site. Signed-off-by: Daniela Engert <dani@ngrt.de>
