+Subject: kernel32: Check for invalid filename pointers in CreateFileA in Win
+ 9X mode.
+
+The demo version of Test Drive 5 loops through a list of filenames and opens
+them using CreateFileA. The stop condition is not correct and the game reads
+past the end of the array and therefore passes several invalid pointers to
+the CreateFileA API. Windows 98 catches those invalid pointers and the game
+can load sucessfully. This commit adds the same behavior when setting the
+Windows version to 9X.
