# Version   Who   Date     Description
#           APY   10/03/00 Error filtering
#                 20/03/00 LEAVETMP shall leave .src files
#                 22/03/00 NODEPDIRS
#                 05/06/00 __SOURCE__
#                 26/02/02 Build system +v2 support.
#                          - ; appended to several directives, forcing use of
#                         'sh.exe' during execution.  Required by WIN32
#                          toolsets (see xx_term variables),
#                          - added depend post processing to append OBJDIR
#                 27/05/02 - realpath
#                          - quoted __SOURCE__, unquoted broke MRI 4.4
#                 12/03/04 mkdepend -b -o -p
