	We have installed IV3.0 and fixed up to patch 8.
	I still have a problem linking in the graphics library
	stuff for an old application. To check It was not my code 
	I tried the old 2.6 example "graphics". I have seen
	articles reporting the same problem but the reported fix
	doesn't help.

        The following is the new Imakefile:
---------------------------------------------------

        #ifdef InObjectCodeDir

        SRCS = *.c
        OBJS = graphics.o
        Use_2_6()
        Use_libInterViews()
        Use_libgraphic()

        ComplexProgramTarget(newgraphics)

        MakeObjectFromSrc(graphics)
        #else

        MakeInObjectCodeDir()

        #endif /* if compiling in subdirectory */

---------------------------------------------------------
The output from make is :

CC +p    -O     -Dcplusplus_2_1 -Div2_6_compatible    -I..
-I/usr/local/InterViews/include/InterViews/2.6
-I/usr/local/InterViews/include/IV-look/2.6
