I was getting

when trying to link the libg++ tests, with G++ 1.34.0+ configged for
sun4-os4. Michael Tiemann recognized these symptoms as:
>when I tried linking crt0+.o which was compiled with a 68020 or a VAX

This diagnosis was close enough to point me in the right direction:
"config" is not enough! there are lines in the makefile (which perhaps
should be ifdefs in ld.c?) with -DTARGET=SUN3 and -DSUN=3 which need
to be hand tweaked (well, comment out the Sun3 line, uncomment the
Sun4 line) when moving form Sun3 sources to Sun4 sources. I had
forgotten to do this when doing the config... 

So, it works, C++ for the Sun4 is a reality, though the configuration
could be automated a little more (though frankly I'd rather see
Multiple Inheritence :-) so maybe a reminder of this line (ok, if I
missed it put it in boldface :-) should be in g++.texinfo.
