Hi, Tom! > Oops, I broke it. Akim checked in the fix. Now it works. I can use "--Werror --add-missing". Thank you for taking care of the problem! The next thing I tried was adding "--Werror" to the automake flags in tests/defs. Just four tests now fail unexpectedly (due to warnings that are now errors): condincl.test dash.test include.test texinfo8.test Warnings are: Use of uninitialized value in pattern match (m//) at ../../automake line 6570. (first three tests) Use of uninitialized value in split at ../../automake line 3185. (texinfo8.test) When they are fixed it will be possible to use "--Werror" in the testuite. Or we can just add those tests to XFAIL_TESTS and enable "--Werror" now. -- Regards, Pavel Roskin
