If a machine can execute it, it can be reverse engineered. It all
depends on how much effort it is worth someone to figure it out. It
takes some good assembler skills to do it, which seems to be rare
these days <g>, so just compiling the code with optimization on will
probably be good enough. If it absolutely, positively must be secure,
then you'll need to encrypt the object code with a strong crypto
algorithm, and make sure the key for it is not available to the
crackers.
