Don't instantiate structures with FAMs.
Since structures with `flexible array members' are an incomplete datatype ANSI C99 forbids creating instances of them. This patch removes such an instance from `diff-lib.c' and replaces it with a pointer to a `struct combine_diff_path'. Since all neccessary memory is allocated at once the number of calls to `xmalloc' is not increased. Signed-off-by: Florian Forster <octo@verplant.org> Signed-off-by: Junio C Hamano <junkio@cox.net>
