>Description:

 	/usr/include/sys/socket.h uses a macro called ALIGN (used by CMSG_DATA)
	but never defines one nor an additional header is included 
	(<machine/param.h> has an ALIGN-macro).
	This circumstance causes the compiler to assume ALIGN is a function
	and the linker to fail.

>How-To-Repeat:

	I hope the description makes it obvious :-)
>Fix:

	Either give socket.h an own ALIGN-macro or include <machine/param.h> in
	socket.h to use the ALIGN-macro of param.h. Or tell all the guys
	using socket.h-functions to include <machine/param.h> first.
	I prefer providing socket.h with an own macro, for example the one
	from <machine/param.h>
