1097 * depends on (recursively). This is somewhat complicated due to the fact that
1098 *
1099 * - we have to respect the module dependencies, i.e. modules implicitly
1100 * referenced by another module have to be initialized before the module
1101 * itself can be initialized
1102 *
1103 * - the initialization routine of a DLL can itself call LoadLibrary,
1104 * thereby introducing a whole new set of dependencies (even involving
1105 * the 'old' modules) at any time during the whole process
1106 *
1107 * (Note that this routine can be recursively entered not only directly
1108 * from itself, but also via LoadLibrary from one of the called initialization
1109 * routines.)
1110 *
1111 * Furthermore, we need to rearrange the main WINE_MODREF list to allow
1112 * the process *detach* notifications to be sent in the correct order.
1113 * This must not only take into account module dependencies, but also
1114 * 'hidden' dependencies created by modules calling LoadLibrary in their
1115 * attach notification routine.
1116 *
1117 * The strategy is rather simple: we move a WINE_MODREF to the head of the
1118 * list after the attach notification has returned. This implies that the
1119 * detach notifications are called in the reverse of the sequence the attach
1120 * notifications *returned*.
