The BSD license says that
* Copyright (c)
*
* Permission to use, copy, modify, and distribute this software for any
* purpose with or without fee is hereby granted, provided that the
* above copyright notice and this permission notice appear in all
* copies
That says, under my interpretation,
1) That distributing only object files complies with the license,
2) That any derived code must retain the exact notice, and for that reason,
3) The copyright holder of the object files is the original author even
if the compiler is a third party person
