I'm the one doing work on getting current GCC compile *all* of
NetBSD/m68k.  I'm quite sure doing cross-compiles to this platform
will work well when 2.7.1 is released.  If someone finds a problem
with this, please mail me, I'll probably fix it right away unless it's
some host-related thing (like compiling on an alpha, 64->32 bit cross
compilation has some known non-trivial to fix bugs, I recall).  Note,
this is only the compiler, I may go on to get current gas & binutils
to work for cross-compilation as well, but I cannot guarantee that,
unless I get a sponsor (hint! ;-) ).  The traditional problem with
cross-assembling & linking is endian problems, I don't know if the
NetBSD tools deal well with this...

Summary: don't worry about the compiler, 2.7.1 should soon be out, and
should do well in this respect.  I have also committed myself to fix
any problems with NetBSD/m68k as target that comes up.

In return I'd like to get to know of any cross-compilation efforts
done and the outcome of them.  I've tried this once before, about a
year or two ago, but then it failed miserably, mostly due to the poor
GCC support for the PowerPC as a host.  Nowadays it's much better in
that area, but I haven't got the time to start that project again.
