3702 | What I have found for non console applications (entry not _mainCRTStartup) | |
3703 | is that the .obj that contains mainCRTStartup is brought in since it is | |
3704 | the first encountered in libc.lib and it has other symbols in it which will | |
3705 | be pulled in by the link process. To avoid this, adding -u with the entry | |
3706 | point name specified forces the correct .obj to be used. We can avoid | |
