1182 * referenced by another module have to be initialized before the module

1185 * - the initialization routine of a DLL can itself call LoadLibrary,
1186 * thereby introducing a whole new set of dependencies (even involving

1189 * (Note that this routine can be recursively entered not only directly

1193 * Furthermore, we need to rearrange the main WINE_MODREF list to allow

1195 * This must not only take into account module dependencies, but also
1196 * 'hidden' dependencies created by modules calling LoadLibrary in their
1197 * attach notification routine.
1199 * The strategy is rather simple: we move a WINE_MODREF to the head of the
