As mentioned on IRC some time ago, Clang suppresses warnings in macros expanded
from definitions in system headers on a case-by-case basis, i.e. some warnings
are suppressed (if someone deliberately enabled suppression), some are not. As
seen here, -Wcast-align is among those warnings that are not suppressed.
