#      ChangeLog
#
#      Wensong        :   Modified the Makefile and the spec files so
#                     :   that rpms can be created with ipvsadm alone
#      P.Copeland     :   Modified the Makefile and the spec files so
#                     :   that it is possible to create rpms on the fly
#                     :   using 'make rpms'
#                     :   Also added NAME, VERSION and RELEASE numbers to
#                     :   the Makefile
#      Horms          :   Updated to add config_stream.c dynamic_array.c
#                     :   Added autodetection of libpot
#                     :   Added BUILD_ROOT support
#      Wensong        :   Changed the OBJS according to detection
#      Ratz           :   Fixed to use the correct CFLAGS on sparc64
