The patch improves size of adler32 (and several other files in zlib) by about
2%. However, overall on the whole csibe it is neutral (the sum of the sizes of
all the files increases by 0.02%) -- the changes in size of the files range
from 7.5% improvement to 7% regression. I did not investigate the cause of the
regressions yet.
