 Current status:
 
 alpha-netbsd:
 
 	* sigtramp_offset, pc_in_sigtramp: 1.4, 1.5, 1.6, post-1.6
 	* sigcontext_addr: post-1.6
 	* skip_sigtramp_frame: post-1.6
 
 arm-netbsd*:
 
 	* no signal support yet
 
 i386-netbsd*:
 
 	* pc_in_sigtramp: 1.6, post-1.6
 	  In 1.4 and 1.5, %fs and %gs are futzed with in the frame,
 	  and things change based on the presence of the VM86 option.
 	* sigcontext_addr: 1.4, 1.5, 1.6, post-1.6
 
 m68k-netbsd*:
 
 	Needs overhaul -- ignoring this for now.
 
 mips-netbsd:
 
 	* pc_in_sigtramp: 1.4, 1.5, 1.6, post-1.6
 	* sigcontext_addr: MIPS target does not use this.  But it is
 	  worth noting that post-1.6, there is no longer a 16-byte gap
 	  before the sigcontext structure.
 
 ns32k-netbsd:
 
 	Needs overhaul -- ignoring this for now.
 
 powerpc-netbsd:
 
 	* no signal support yet
 
 sh-netbsd:
 
 	* pc_in_sigtramp: post-1.6
 
 	This target needs more attention paid to it, in general.
 
 sparc*-netbsd*:
 
 	* pc_in_sigtramp: post-1.6
 	  Signal trampolines on NetBSD/sparc are nearly impossible
 	  to identify because they're so huge.  Consider comparing
 	  addresses on this platform (VM layout can't really change
 	  on Sun4/Sun4c/Sun4m [except MicroSPARC-IIep]).
 
 	This target needs more attention paid to it, in general.
