+  * harbour/bin/hb-func.sh
+    * updated list of system libraries used in to create harbour*.dll
+      in MinGW builds
+
+  * harbour/bin/postinst.sh
+    - removed not longer used code for build library in postinst phase
+    * use 'suncc' instead of 'cc' to create harbour shared library without
+      any platform dependent non default settings
+    * synced flags used in build process with flags used to create
+      harbour shared library in sunpro builds
+
+  * harbour/config/linux/sunpro.cf
+  * harbour/config/sunos/sunpro.cf
+    * removed options which explicitly force platform
+    * added -xbuiltin=%none as workaround for problems in x86 PIC builds
+      exploited by hbpcre library code
+    * changed the order of C/LD flags settings so they can be easy
+      overwritten by HB_ISAOPT
