For 3.2.1, we have successful reports for sparc-sun-solaris2.6, both
with binutils and with native as and ld.  There were some issues with
earlier 3.x releases.

Generally speaking, anything that no one has tested for a while tends to
break, especially for older OSes that have peculiarities that must be
worked around (e.g. SunOS).  The good news, however, is that the breakage
often has a trivial fix.  So don't lose hope if you get a failure, instead
please ask for help, showing the exact failure that you get.  Also,
cross-compilation tends to be a bit tricky, and some things are different
now; better to ask for help than to suffer alone.

Joel Sherill reported successful builds for m68k-elf and m68k-coff for
gcc 3.2.1 + binutils 2.13.1; see

http://gcc.gnu.org/ml/gcc/2002-12/msg00326.html

He didn't say anything about m68k-aout, perhaps because he had no
interest.
