  Log:
  Newer versions of gcc don't support treating structures passed by value
  as if they were really passed by reference. Specifically, the dead stores
  elimination pass in the GCC 4.1 optimiser breaks the non-compliant behavior
  on which FreeBSD relied. This change brings FreeBSD up to date by switching
  trap frames to being explicitly passed by reference.
