- the -u switch if they were specifying an entry point other than
- _mainCRTStartup. Specifically, if creating a windows application, entry
- point _WinMainCRTStartup must be specified.
- What I have found for non console applications (entry not _mainCRTStartup)
- 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
