Thanks for the report.
You should be able to cause "make check" to pass in that case
by creating a symlink for each classic name to its prefixed version, e.g.,

  cd src && for i in grep egrep fgrep; do ln -fs g$i $i; done

You're the first to report this, so for now, I'll simply mark this
issue as closed.
By the way, that reversed-range-endpoints test need not use egrep,
since it already tests 'grep -E', so I have fixed that.
