Use "standard" int main in Windows builds

Using WinMain is not necessary in order to get access to the "wide" command
line, and makes the MSVCRT skip all the initialisation steps needed for
"Console API" to work correctly, leading to the program having no output in
Windows console programs that use it - most notably, cmd.exe.
