C++ question

[Shao Zhang]

Hi, 
        I have posted this to comp.lang.c++, but hope someone here can
        help me as well. Thanks.

=====================
        I have a c++ program that compiles fine with
        earlier version of g++, but it no longer compiles with
        the newsest release 2.95.2.

        Here is the relevant bit of code:

        typedef struct List
        {
                void            **hd;   /* first item */
                void            **cr;   /* current item */
                void            **tl;   /* last item */
                void            **mx;   /* max item before growing is required 
*/
                int             grow_size;
        } List;

        Some macros defined:

        #define fast_list_first(l)      ((l && l->hd)? *(l->cr = l->hd) : 0)
        #define fast_list_last(l)       ((l && l->hd)? *(l->cr = l->tl) : 0)

        And a Function like this:
        void lfree(List *l)
        {
                void *item;
                for (item=fast_list_first(l); item != NULL; 
item=fast_list_last(l))
###->>>>                delete item;
        }


        When compiled with g++(2.95.2), it failed with this:
        [line 55 is the line marked with arrows above]
        % g++ -g -c misc.c
        misc.c: In function `void lfree(List *)':
        misc.c:55: warning: `void *' is not a pointer-to-object type

        It gives me the warning message, but no .o file is created, and
        if I put it in a makefile, it results:
        % make misc.o
        g++ -g -c misc.c
        misc.c: In function `void lfree(List *)':
        misc.c:55: warning: `void *' is not a pointer-to-object type
        make: *** [misc.o] Error 1


        Thanks for any help in advance.

Shao.
