undefined reference to `_ctype_' using newlib-1.10.0 under CygWin

[J. Johnston]

Other than suggesting you move to a more recent version of newlib,
you need:

   m68*)
         machine_dir=m68k
         newlib_cflags="${newlib_cflags} -DCOMPACT_CTYPE"
         ;;

in your configure.host.  It is the -DCOMPACT_CTYPE flag that you need to add.
You will have to rebuild the libc/ctype directory.
