Clean up the code in bin/ to reduce warnings from GCC3. Stage 2 of 5 or so: small cleanups across several programs. - Convert ``quad'' types to ``long long''. - Convert appropriate ``int'' types to ``size_t''. - Fix comment syntax to use /* */ instead of //. - Initialize a variable before using it. - Remove an unneeded cast.
