I haven't changed anything with configuring in the opcodes
directory. I see the same error as you when I configure for
"z8k-coff", but configuring for "z8k-anything-coff" works fine.

I thought the configure targets are triples, so z8k-coff shouldn't be
valid anyway?

Most embedded toolchains use doubles, since there is no one specific
system that they are targeted towards.

Many target duples work.  "./config.sub <target>" to see what happens.
Read the start of config.sub to see where you should send patches, should
you desire to make "z8k-coff" work.

Here broken means ``it doesn't build''. If it builds but dumps core when
you try to run it then that just means that it doesn't work very well
;-)

Using current sources I'm seeing:

*** BFD does not support target z8k-coff.
*** Look in bfd/config.bfd for supported targets.
Configure in /home/scratch/GDB/X-z8k-coff/opcodes failed, exiting.

Since src/opcodes is shared with GDB, your changes will fix this part of
GDB as well.

For GDB 5.1, I'll document the z8k as broken.  If the build problems get
resolved, let the GDB group know (gdb@sources.redhat.com).  The files
gdb/TODO and gdb/MAINTAINERS can then be updated to reflect that changed
reality.

Yes, that is correct usage.

Good luck.
