-// Runtime check of the assumptions about the size of builtin types,
-// memory model, byte order and other low-level constructs.
-//
-// We are really paranoid here - LZO should either fail
-// at startup or not at all.
-//
-// Because of inlining much of these functions evaluates to nothing.
-//
-// And while many of the tests seem highly obvious and redundant they are
-// here to catch compiler/optimizer bugs. Yes, these do exist.
