bchop - performs a binary chop between "good" and "bad" object modules

bchop performs a binary chops between object files in two directories (./good and ./bad) compares the output and isolates which object file is causing the difference in output. This helps isolate problems due to changing compiler or preprocessor options. The number of trials performed is approximately 2Elog₂(N), where N is the number object files and E is the number of object modules causing the errors (The -1 option forces the number of comparisons to be exactly N).
