function "prratio()" in sources to BSD compress

[James A. Woods]

good eye.
the original was floating point, like your suggestion, and
i wrote it knowing the floats were not a cpu drain.

it was changed by ken turkowski (still of apple?) to accomodate
a pdp 11 without floating point hardware.

i agree that it should revert to floating point.

better yet would be to speedup dan bernstein's 'squeeze',
a miller/wegman/ziv/lempel coder which has better c-rates. 

ames!jaw
