MSVC problem with gen-getopt.py

Two of generated .h-files in ./src does not work with MSVC; certtool-options.h and psktool-options.h:

psktool-options.h(55): error C2016: C requires that a struct or union have at least one member

I.e. for this code:

  /* Option enablement status */
  struct
  {

  } enabled;

A fix for me was to modify gen-getopt.py to insert some int dummy; statements for such empty lists:

But I'm not sure how a proper fix would look like.
