compat.safeint.lua

-- Form B inline descriptor for SafeInt — header-only checked integer arithmetic.
--
-- Upstream ships two independent public APIs:
--   * SafeInt.hpp   — the C++ SafeInt<T> class;
--   * safe_math.h   — checked C arithmetic over 32- and 64-bit integers.
--
-- Both headers, and safe_math.h's safe_math_impl.h, sit at the archive root,
-- exactly like upstream's INTERFACE include directory. A trivial anchor TU
-- gives mcpp a buildable lib target, following the compat.gtl / compat.eigen
-- shape. There are no optional compilable components to expose as features.
--
-- safe_math.h deliberately rejects a translation unit that has already
-- included SafeInt.hpp, so these APIs must be consumed from separate TUs.
-- A C++ TU using only the C API should wrap #include <safe_math.h> in
-- extern "C"; this keeps upstream's prototype and inline definitions on the
-- same linkage.
