It seems that __STDC_ISO_10646__ isn't defined even where it can be
defined, so remove the check for it and leave it up to people compiling
the software (DOWNSTREAM) to take care of this.  This will eventually
need to be fixed up with a proper non-10646 converter and so on, but
this is a simple start.  While here, strengthen then language in the
Makefile to this effect.
