2843 | What I have found for non console applications (entry not _mainCRTStartup) | |
2844 | is that the .obj that contains mainCRTStartup is brought in since it is | |
2845 | the first encountered in libc.lib and it has other symbols in it which will | |
2846 | be pulled in by the link process. To avoid this, adding -u with the entry | |
