Why are we writing code like this?

struct font_driver const nsfont_driver =
  {
  type: LISPSYM_INITIALLY (Qns),
  case_sensitive: true,
  ...
  };

and not like this?

struct font_driver const nsfont_driver =
  {
  .type = LISPSYM_INITIALLY (Qns),
  .case_sensitive = true,
  ...
  };

The former is a deprecated GCC extension.  The latter is the standard.
We need C99 these days anyway.
