+
+  * harbour/utils/hbmk2/hbmk2.prg
+    * use DOS/4G for DOS OpenWatcom binaries instead of causeway which seems
+      to have some troubles with executing child processes. At least in
+      FreeDOS inside DOSEMU.
+      Warning DOS/4G reduce maximal size of command line. Ideal seems to
+      be PMDEV but it's not free for commercial use though we can think
+      about using it to create Harbour binaries.
