 192  *
 193  * - we have to respect the module dependencies, i.e. modules implicitly
 194  *   referenced by another module have to be initialized before the module
 195  *   itself can be initialized
 196  *
 197  * - the initialization routine of a DLL can itself call LoadLibrary,

 199  *   the 'old' modules) at any time during the whole process
 200  *
 201  * (Note that this routine can be recursively entered not only directly
 202  *  from itself, but also via LoadLibrary from one of the called initialization
 203  *  routines.)
 204  *
 205  * Furthermore, we need to rearrange the main WINE_MODREF list to allow
 206  * the process *detach* notifications to be sent in the correct order.
 207  * This must not only take into account module dependencies, but also
 208  * 'hidden' dependencies created by modules calling LoadLibrary in their
 209  * attach notification routine.
 210  *
 211  * The strategy is rather simple: we move a WINE_MODREF to the head of the
 212  * list after the attach notification has returned.  This implies that the
 213  * detach notifications are called in the reverse of the sequence the attach
 214  * notifications *returned*.
