I think we should start using -Wmissing-field-initializers in samba3 and
samba4. So that we at least notice when the number of members don't match.

- -Wmissing-field-initializers
  Warn if a structure's initializer has some fields missing.
  For example, the following code would cause such
  a warning, because "x.h" is implicitly zero:

                   struct s { int f, g, h; };
                   struct s x = { 3, 4 };

  This option does not warn about designated initializers, so the
  following modification would not trigger a warning:

                   struct s { int f, g, h; };
                   struct s x = { .f = 3, .g = 4 };

  This warning is included in -Wextra.  To get other -Wextra warnings
  without this one, use -Wextra -Wno-miss-ing-field-initializers.
