3231 | What I have found for non console applications (entry not _mainCRTStartup) | |
3232 | is that the .obj that contains mainCRTStartup is brought in since it is | |
3233 | the first encountered in libc.lib and it has other symbols in it which will | |
3234 | be pulled in by the link process. To avoid this, adding -u with the entry | |
3235 | point name specified forces the correct .obj to be used. We can avoid | |
3236 | making the user do this by always adding the entry point name as an | |
3237 | undefined symbol. */ | |
