According to FreeBSD man page for sigaction
(http://www.freebsd.org/cgi/man.cgi?query=sigaction&apropos=0&sektion=0&manpath=FreeBSD+5.4-RELEASE+and+Ports&format=html)
 the following looks like it should fix it.

	* init.c (FreeBSD's __gnat_install_handler): Cast
	__gnat_error_handler to proper type.
	* link.c (FreeBSD's __gnat_object_file_option,
	__gnat_run_path_option, __gnat_object_library_extension): Make
	const.

This issue can be closed as the code in init.c has changed and those warnings
have been taken care of.
