Bonjour,

Ça semble en effet être une microsofterie, apparemment liée à l'utilisation
de bibliothèques de liens dynamiques (DLL).

Par exemple je trouve ceci en faisant une recherche sur « prefix __imp_ » :

<https://stackoverflow.com/questions/5159353/how-can-i-get-rid-of-the-imp-prefix-in-the-linker-in-vc>

<cit.>
The __imp__ prefix appears whenever you are linking to a DLL. It does not appear
when linking to statically linked libraries. Most likely the code is generated
to be linked against a DLL import lib, but you have linked it with a static lib
instead.

The prefix is added when you mark the imported function with
__declspec(dllimport) - make sure your imports are not using this when not
linking against a DLL.
