Looks like -Wnon-literal-null-conversion is intended to warn for the comparison
case too, though it doesn't seem to be implemented yet as of clang 3.4:

--- Comment #3 from Ulf Magnusson ulfalizer at gmail dot com ---
clang also generates a warning for C programs with void *a = '\0' by the way,
so it seems to be able to look at the form of the integral constant there.

--- Comment #4 from Jonathan Wakely redi at gcc dot gnu.org ---
Yes, although C says '\0' has type int the compiler can still distinguish the
token '\0' from 0 during compilation.
