This is correct.  You export `define' but you never define it.

That is correct as well, since there is no definition for `unquote'
and `unquote-splicing'.

The fix is to use `re-export' and not export `unquote' etc.  Also,
safe-.r5rs.scm should use re-export, except for `null-environment'
which has a proper local definition.  I have fixed this.

I noticed that we don't have `rationalize', `numerator' and
`denominator', but we should even if we don't have rationals.
