I've found http://www.gregorpurdy.com/gregor/ltag/
helpful in guessing CVS tags.  It reduces the search space considerably.
(It might not help much when matching up different modules, though...)

I've noticed that, when you start trying to use the testsuites, you have
to pay closer attention to the build/host/target names you use.

It looks like the name arm-uclinux is in use, and makes more sense than
arm-elf, at least to me; see
http://gcc.gnu.org/ml/gcc-patches/2000-01/msg00216.html
http://sources.redhat.com/ml/binutils/2001-10/msg00564.html
http://www.uclinux.org/pub/uClinux/archive/5837.html
I'd expect m68k-uclinux to also be popular?

I wouldn't be suprised if you had to call your target m68k-unknown-uclinux-gnu
to make e.g. binutils' or gcc's test suite happy.  Dejagnu tends to get
upset if you don't have several dashes in the target :-)

Be sure to use a recent version of inetutils.  Older ones
didn't set the environment properly in rshd.  BTW you need all three,
probably: rshd, rlogind, and rcp.

Hopefully this'll shake out a few bugs in gcc-3.3.1 before release...
or more likely, in 3.4, if you test that...
