+ Actions to perform at very early stage of KDE application life on MS Windows.
+ Currently not much is performed here but later, who knows...
+
+ Additional algorithm for win9x (including Millenium), where are problems with 
+ easy setting environment variables:
+
+ - try to find HOME env. variable
+ - if not found, try to find USERPROFILE env. variable
+ - if not found, try to find both HOMEDRIVE and HOMEPATH env. variables
+ - if not found, try in the Windows Registry:
+   - try get 'Software\KDE' value from HKEY_CURRENT_USER section of Windows Registry
+   - if not found, try to get from 
+     'Software\Microsoft\Windows\CurrentVersion\Explorer\Shell Folders\AppData'
+   - if one of above two found, put the value as HOME environment variable 
+     using putenv() function.
+
+ Once HOME variable is set, Qt handles it well.
