I run it like:

--8<---------------cut here---------------start------------->8---
./meta/guile -L test-suite -L . test-suite/tests/compiler.test
--8<---------------cut here---------------end--------------->8---

And I see:

--8<---------------cut here---------------start------------->8---
ERROR: compile-file: relative include works with load path canonicalization - arguments: ((system-error "open-file" "~A: ~S" ("Aucun fichier ou dossier de ce type" "./hello/hello-impl.scm") (2)))
--8<---------------cut here---------------end--------------->8---

That's the include directive failing because scm_i_relativize_path
caused the path to be stripped from "../module/hello.scm" to
"hello.scm"; then include, through its call-with-include-port helper,
calls (dirname "hello.scm"), which produces ".".

Finally, the same helper calls (in-vicinity "." "hello/hello-impl.scm"),
which produces the unresolvable "./hello/hello-impl.scm" file name seen
in the error above.
