See this commit: https://cgit.git.savannah.gnu.org/cgit/texinfo.git/commit/?id=19cf2ac6fa4fb238257cc52a5df93f36ec4937c8 I added enable_xs to ModulePath.pm.in, a BEGIN block in test_utils.pl and modified the existing texi2any.pl BEGIN block to set disable_XS too. Now I realize that the tests in tta/perl/t/z_misc/*.t are not covered. For some reason it did not show up in my test, I'll double check. -- Pat
