tm-define migration problem

[da-liii]

at this commit https://github.com/sadhen/texmacs/commit/b54364bbd2fc4344895ab06cb35a90c2f6329e22

we can use tm-define in init-texmacs.scm, but at next step, when I try to make tm-preferences.scm compile, it fails and says (since it works in init-texmacs.scm, there are hopes to make it work):

;;; WARNING: compilation of /home/sadhen/software/share/TeXmacs/progs/kernel/texmacs/tm-preferences.scm failed:
