--- Comment #2 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Can't reproduce with gcc version 6.3.1 20161221 (Red Hat 6.3.1-1) (GCC) nor
current trunk. Perhaps the flags you've listed are incomplete? There is no
-Wall nor -Wcomment nor -Wall -Werror nor -Werror=comment, so it certainly
doesn't warn with the flags you've mentioned.
It might be better if you attach the testcase, so that tabs vs. spaces are
preserved.
