Amber 8 on Solaris 7

Use Workstation v6u2 compilers, not v5 to avoid

For the parallel bit, add -I/opt/SUNWhpc/include and -L/opt/SUNWhpc/lib to config.h in a few places:

    CPPFLAGS= $(AMBERBUILDFLAGS) -I/opt/SUNWhpc/include

    FPPFLAGS= -P -I$(AMBER_SRC)/include -I/opt/SUNWhpc/include -DMPI  $(AMBERBUILDFLAGS)
    FFLAGS= -O1 -I/opt/SUNWhpc/include -L/opt/SUNWhpc/lib $(LOCALFLAGS) $(AMBERBUILDFLAGS)
F

    export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/opt/SUNWhpc/lib
    make parallel

The X-related part of Amber v8 won't compile out of the box on Solaris 7. As per usual the /usr/openwin/include files are the problem. The following bodges fix things.

added

    #define _Xconst const

to Atoms.h, CharSet.h, SysUtil.h, Xct.h and WidgetNode.h below

    #include <X11/Xfuncproto.h>

added

    #include <stdio.h>
    typedef unsigned long Pixel;
    #define _Xconst const

to Drawing.h below

    #if NeedFunctionPrototypes
    .

    #endif
