  The consensus used to be that such a beast did not, *could* 
not, exist.  A 
rudimentary grasp of compiler technology clearly supports 
this conclusion.

There have been "decompilers" for years.  What they generally do is just
turn the binary to assembler or if they're really fancy a C program, though
the program will look nothing like the original.  If you use one of these
plan to spend a LOT of time going through the code and don't expect it to be
much more reader-friendly than straight assembler even if you manage to get
it to look like C.
