+  * src/rtl/filesys.c
+    + fs_win_set_drive(): Setting SEM_FAILCRITICALERRORS before
+      SetCurrentDirectory() call to avoid screen msg in some error
+      scenarios. Thanks to vbdasc (final patch has two modifications,
+      so pls retest it).
+    + hb_fsChDir(): Applied similar logic as above.
+    * Using FALSE instead of 0 in both function above.
+
+  * contrib/hbssl/evppkey.c
+    * Comment.
