// Ensure that this macro definition stays in a private header file: clang
// suggests the first macro expanding to [[clang::fallthrough]] in its
// diagnostics, so if BP_FALLTHROUGH is visible in code depending on breakpad,
// clang would suggest BP_FALLTHROUGH for code depending on breakpad, instead of
// the client code's own fallthrough macro.
// TODO(thakis): Once everyone uses C++17, use its [[fallthrough]] instead.
