+  * INSTALL
+    + Added minimum tested version of MinGW.
+
+  * make_gnu.bat
+    + Added echo to display errorlevel after running GNU Make
+      if it's not zero. Eventually I'd like to add proper
+      error display in case GNU Make returned with error
+      (not that GNU Make doesn't display it), but first I'd
+      like to inspect how it works (there is no documentation
+      about returned errorlevels).
+
+  * config/win/mingw.cf
+    ! Fixed 'del' command receiving wrongly formed path seps
+      in non-msys mode when lib creation failed.
+
+  * ChangeLog
+    ! Typo in one yesterday's entry.
