* aoutf1.h (struct external_sparc_core): Declare c_regs as struct

	regs instead of an array of int.
	(struct external_solaris_bcp_core): Likewise.
	(swapcore_sun3): Use offsetof instead of computing the offset
	manually.
	(swapcore_sparc): Likewise.  Simplify reference to c_regs.
	(swapcore_solaris_bcp): Likewise.
