Well most of you were right and my pride blinded me to the problem :-)

I had malloc'd memory for the list nodes according to the
sizeof(Pointer_to_struct) instead of sizeof(structure_node)

The strange thing is that Linux-gcc let me do this and it worked. I
was suspicious of the DJGPP/gcc compiler but I think now that the
behaviour of the DJGPP compiler was correct.

Thanks to all who responded and I think I'll get a copy of Lint.
