+ is that the .obj that contains mainCRTStartup is brought in since it is
+ the first encountered in libc.lib and it has other symbols in it which will
+ be pulled in by the link process. To avoid this, adding -u with the entry
+ point name specified forces the correct .obj to be used. We can avoid
+ making the user do this by always adding the entry point name as an
