I still get a couples of failures while running tests : - test/src/editfns-tests.log Test format-time-string-with-zone condition: (ert-test-failed ((should (string-equal (format-time-string format look -28800) "1972-06-30 15:59:59.999 -0800 (-08)")) :form (string-equal "1972-06-30 15:59:59.999 -0800 (ZZZ)" "1972-06-30 15:59:59.999 -0800 (-08)") :value nil)) It is a new failure for a new test introduced by: commit 541006c53623cb5fb7dfae475baae5d64fc6e9d0 Clearly, the timezone is wrongly formatted. - test/lisp/ibuffer-tests.log Test ibuffer-filter-inclusion-8 condition: (file-error "Creating file with prefix" "Invalid argument" "c:/Users/Fabrice/AppData/Roaming/Local/Temp/ibuf-test8c") FAILED 11/19 ibuffer-filter-inclusion-8 I don't see how create-file-buffer in this test can ever create a temp file ending with an '*'. But I am probably overlooking something. Does it pass on other platforms ? Fabrice
