+ * - 16bit mmTaskXXX functions are currently broken because the 16
+ *   loader does not support binary command lines => provide Wine's
+ *   own mmtask.tsk not using binary command line.
+ * - correctly handle the MCI_ALL_DEVICE_ID in functions.
+ * - finish mapping 16 <=> 32 of MCI structures and commands
+ * - implement auto-open feature (ie, when a string command is issued
+ *   for a not yet opened device, MCI automatically opens it) 
+ * - use a default registry setting to replace the [mci] section in
+ *   configuration file (layout of info in registry should be compatible
+ *   with all Windows' version - which use different layouts of course)
