1 Compress version 4.0 improvements over 3.0:
2 o compress() speedup (10-50%) by changing division hash to xor
6 o Removed 'Big+Fast' compress code (FBITS) because of compress speedup
24 The following preprocessor symbols control the compilation of "compress.c":
57 a version of compress on a smaller machine cannot be decompressed! Use the
61 The output of compress 4.0 is fully compatible with that of compress 3.0.
62 In other words, the output of compress 4.0 may be fed into uncompress 3.0 or
63 the output of compress 3.0 may be fed into uncompress 4.0.
65 The output of compress 4.0 not compatible with that of
66 compress 2.0. However, compress 4.0 still accepts the output of
