Thanks!  It looks like the following native targets use solib-sunos.o
(this works due to init-order for native targets only; a cross-target
would attempt to use solib-svr4.o):

arm*-*-netbsd* (except arm*-*-netbsdelf*)
sparc*-*-netbsd* (except sparc*-*-netbsdelf*)
vax*-*-netbsd* (except vax*-*-netbsdelf*)

  None of those define DECR_PC_AFTER_BREAK.

i[34567]86-*-netbsd* (except i[34567]86-*-netbsdelf*)
i[34567]86-*-openbsd[0-2].* | i[34567]86-*-openbsd3.[0-3]

  These define DECR_PC_AFTER_BREAK to 1.

m68*-*-netbsd* (except m68*-*-netbsdelf*)
m68*-*-openbsd*

  These define DECR_PC_AFTER_BREAK to 2, as you point out.

Bye,
Ulrich
