Thanks. But now, in m4, there is a "make distcheck" failure: $ make distcheck ... (cd po && make top_distdir=../m4-2021-05-16 distdir=../m4-2021-05-16/po \ am__remove_distdir=: am__skip_length_check=: am__skip_mode_fix=: distdir) make[3]: Entering directory '/M4/m4-branch-1.4/po' test -z "update-po" || make update-po make[4]: Entering directory '/M4/m4-branch-1.4/po' make m4.pot-update make[5]: Entering directory '/M4/m4-branch-1.4/po' make[5]: *** No rule to make target '../lib/verror.c', needed by 'm4.pot-update'. Stop. make[5]: Leaving directory '/M4/m4-branch-1.4/po' make[4]: *** [Makefile:520: update-po] Error 2 make[4]: Leaving directory '/M4/m4-branch-1.4/po' make[3]: *** [Makefile:491: distdir] Error 2 make[3]: Leaving directory '/M4/m4-branch-1.4/po' make[2]: *** [Makefile:2569: distdir-am] Error 1 make[2]: Leaving directory '/M4/m4-branch-1.4' make[1]: *** [Makefile:2563: distdir] Error 2 make[1]: Leaving directory '/M4/m4-branch-1.4' make: *** [Makefile:2670: dist] Error 2 An update of po/POTFILES.in is in order, I think. Like you did in coreutils. Bruno
