As I already mentioned:

Just use this infos:
hdll = LoadLibraryA("libwine.dll");
wine_dlopen = GetProcAdress(hdll, "wine_dlopen");
wine_dlsym = GetProcAdress(hdll, "wine_dlsym");
wine_dlclose = GetProcAdress(hdll, "wine_dlclose");

Keep attention on the calling convention.

A "*.spec" is used as input for winebuild to build a "*.def".
Keep it as simple as possible and use only grep:
"grep -r dlopen <wine-source>/libs/"
You find the exported functions in "libs/wine/wine.def"
