Actually, I can remember true decompilers for FORTRAN created during the 70s and early 80s. Grad students would build such things during the wee hours. Each different machine had to have it's very own handcrafted version. The binary for a DEC and CDC were very different. As I recall, aside from the lost variable names, (no one commented their FORTRAN code), these programs did quite well in reproducing the original code. Of course by comparison, FORTRAN is a relatively simple language, no classes, simple data structures, etc.

I would be surprised if such custom-made decompilers don't exist for C++. I can't imagine that some kid from M$ with plenty of time at night hasn't coded one up for VC.
