* ui-file.c: Include "gdb_string.h" * cli-out.c: Include gdb_string.h to avoid compiler warnings. * wrapper.[ch] (struct gdb_wrapper_arguments): Change fields into unions, since they are all used to hold both pointers and ints at various times. Casting pointer to int and vice versa gives warnings (and is not safe) if they are not the same size.
