a.out vs. ELF

Hi all,

I'd like to ask maybe trivial question but I couldn't find much
information about it. Does NetBSD/m68k still support a.out? I could
find some traces in
https://www.netbsd.org/docs/elf.html#elf-updating-from-a.out and
http://netbsd.gw.com/cgi-bin/man-cgi?elf2aout+1+NetBSD-7.1 indicating
that a.out is obsolete/replaced/not favoured anymore but if the drop
of a.out happened, when it was?

I ask mainly because I see its support dropped in gcc and gdb (not in
other parts of binutils, though), i.e. whether a.out is gone for good
(it used to be the last working a.out target).

Thanks,
Miro
