I  have  not.  I  was  wrong  regarding  bindings not  being
re-exported (I forgot what my local scripting infrastructure
did);  but I  still get  the "unbound  variable"  error from
Guile.

  The   only   thing   I   can  guess   (after   trying   to
comment/uncomment random forms) is that it is a problem with
the expander possibly in its interaction with compiled code,
because all the other  R6RS implementations work fine.  Also
I have found this: when  I run the test with "--autocompile"
(starting with a clean cache) I get the error:

GUILE_LOAD_PATH=. guile -l guile-r6rs-setup.scm --autocompile -s ./tests/test-annotated-types.sps
;;; note: autocompilation is enabled, set GUILE_AUTO_COMPILE=0
;;;       or pass the --no-autocompile argument to disable.
;;; compiling guile-r6rs-setup.scm
[...]
;;; WARNING: compilation of ./tests/test-annotated-types.sps failed:

guile: uncaught throw to vm-error: (vm-run "VM: Unbound variable: ~s" (#<variable 851b5e8 value: #<undefined>>))
make: *** [gtest] Error 1

but  when  running  with  "--no-autocompile" (with  a  clean
cache) I get:

GUILE_LOAD_PATH=. guile -l guile-r6rs-setup.scm --no-autocompile -s ./tests/test-annotated-types.sps

I do use ASSERT in the code, but I do no strange things with
its binding.   Unfortunately I have  no time to dive  in the
internals of Scheme implementations.
