Git for Windows has special code to retrieve the command-line parameters (and even the environment) in UTF-16 encoding, so that they can be converted to UTF-8. This is necessary because Git for Windows wants to use UTF-8 encoded strings throughout its code, and the main() function does not get the parameters in that encoding. To do that, we used the __wgetmainargs() function, which is not even a Win32 API function, but provided by the MINGW "runtime" instead. Obviously, this method would not work with any other compiler than GCC, and in preparation for compiling with Visual C++, we would like to avoid that. Lucky us, there is a much more elegant way: we simply implement wmain() and link with -municode. The command-line parameters are passed to wmain() encoded in UTF-16, as desired, and this method also works with Visual C++ after adjusting the MSVC linker flags to force it to use wmain().
