1112 * - we have to respect the module dependencies, i.e. modules implicitly
1113 * referenced by another module have to be initialized before the module
1114 * itself can be initialized

1116 * - the initialization routine of a DLL can itself call LoadLibrary,

1119 *
1120 * (Note that this routine can be recursively entered not only directly
1121 * from itself, but also via LoadLibrary from one of the called initialization
1122 * routines.)
1123 *
1124 * Furthermore, we need to rearrange the main WINE_MODREF list to allow
