Curious.  Are you saying that that changed recently in clang?  I wonder
whether clang's warning catches this case on purpose, or whether it's
a regression.  I asked David Malcolm, who added that warning to GCC, and he
said that GCC's implementation respects tab stops, so small numbers of
leading spaces before a tab are effectively ignored.

Thanks,
