this is so that the user

doesn't have to because they would have to use 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 undefined symbol. */
