The List macros appear to have been broken between IV3.1beta3 and IV3.1.
They are given in <OS/list.h>.  I have a working 3.1beta3 program that
complains about the macro in 3.1.

/usr/local/CenterLine/bin/CC     -Dcplusplus_2_1     -I/appl1/iv3.1/installed/include -I/appl1/X11R5/include  -pipe -c ../arcdial.C
CC  ../arcdial.C:
"../arcdial.C", line 17: error:  argument declaration syntax

7 errors
*** Error code 1
make: Fatal error: Command failed for target `arcdial.o'

line 17 is:
implementPtrList(LabelList,ArcDialLabel);

which expands into:
void LabelList::insert(long index, ArcDialLabel* item) { 
    const __AnyPtr p = item; 
    impl_.insert(index, p);
} 
ListItr(LabelList)::ListItr(LabelList)(const LabelList& list) { 
    list_ = &list; 
    cur_ = 0; 
} 

ListUpdater(LabelList)::ListUpdater(LabelList)(LabelList& list) { 
    list_ = &list; 
    cur_ = 0; 
}

The errors occur on the 1st and 3rd lines of the expanded macro.
My program compiles fine under IV3.1 if I include OS/line.h from the
beta3 distribution, so this isn't a big enough problem to spend a lot
of debugging time (on a macro <<groan>>), and I can't tell right off
what the problem is.  For what it's worth, I'm on a Sun 4/330 with
32MB and SunOS4.1.1, using CenterLine CC to compile.

I suggest substituting the beta3 copy of OS/list.h for now.
