I have absolutly no trouble building and using an sh-elf cross compiler
under cygwin, solaris and linux using newlib. I have successfully built
both 3.0 and 3.0.1. As far as I am concerned the target can be added to
the list on the web site.

On the other hand I did have a lot of trouble getting dejagnu working - I
have managed to get it cobbled together after a lot of grief so that it
works. Best of luck fixing it!
