+  * INSTALL
+    + Added MinGW + msys specific entry.
+
+  * bin/postinst.sh
+    + Added generation of hbcc.bat, hbcmp.bat, hblnk.bat
+      to be in complete feature sync with the non-msys method.
+      NOTE: non-msys method isn't recommended.
+
+  * make_gnu_os2.cmd
+    + Added automatic HB_*_INSTALL setup based on HB_INSTALL_PREFIX
+      to be in sync with the rest of Harbour.
+
+  * make_gnu.bat
+    ! Fixed forward slashed to backslashes.
+    * Changed default compiler from mingw to msvc.

+Windows with MinGW + msys
+-------------------------
+   This is the recommended way to build with MinGW.
+
+   Make sure to have msys and MinGW properly installed
+   and setup. msys should be put in PATH _before_ MinGW.
+
+   > set HB_INSTALL_PREFIX=<DIR> (use forward slashes and msys drive notation: /c/)

+   To test it, go to <DIR>/bin directory and type:
+   > hbmk2 ../tests/hello.prg
+   > hello
+   You should see: 'Hello world!' on screen.
+
+Windows with other compilers
+----------------------------
    Make sure to have your C compiler of choice properly
    installed and GNU Make (with the name make.exe)
    accessible in the PATH _before_ the compiler tools.
