I recall someone stating "benchmarking without analysis is bogus".

As a first step, comment out the print statements

time ./latinc

user    0m0.492s
sys     0m0.004


time java Latin

user    0m0.992s
sys     0m0.052s


With the print statements ~5.4x
without print statements ~2.1x

iirc the Java program is shuffling around double byte unicode chars and
the C program is handling single byte chars.
