Put it in the same directory as gdb.  It works for me.

Fine.

I have used --target=powerpc-eabi but I don't think that will make any
difference.  Now that I think of it, I mainly used a dos version of gdb
with bdm pathces by Scott Howard.  I think he has prebuilt mingw32
versions now on his web site.  http://www.objsw.com/

The latest Macraigor OCD software should have the latest wigglers.dll.
