xtract_mfcc(): Slightly different way of limiting to XTRACT_LOG_LIMIT. It's the same in theory, but saves on one assignment operation. But the real reason I did it was because my compiler (gcc 4.0.1, Apple intel edition) was getting it wrong (presumably during some optimisation). It does save on the assignment though.
