On Mac OS X CFBundle knows how to find the absolute path of the
executable.  On Linux one can read the symbolic link /proc/self/exe.
On Windows if you open an app from the GUI, the CWD is the one
containing the executable, but if you run it on the command-line
that's presumably not the case... and on other OSes, I don't know of
any way other than Gordon's suggestion of searching PATH for argv[0].
