[svn-r18759] pull r18757 from 1.8 branch

Enable tools lib to be built as a dll on windows. Added two get/set functions for progname and d_status.
Also add windows import/export declarations to functions.
Updated error_mesg() and warn_mesg() to remove progname argument and use get functions

Tested:
   Windows, linux
