228 _mainCRTStartup. Specifically, if creating a windows
229 application, entry point _WinMainCRTStartup must be
230 specified. What I have found for non console
231 applications (entry not _mainCRTStartup) is that the .obj
232 that contains mainCRTStartup is brought in since it is
233 the first encountered in libc.lib and it has other
234 symbols in it which will be pulled in by the link
235 process. To avoid this, adding -u with the entry point
236 name specified forces the correct .obj to be used. We
237 can avoid making the user do this by always adding the
