271.0.6 downloaded from http://www.bzip.org.

29In an effort to provide ease of syncing with the upstream code, this
30source hasn't changed much. The usual Solaris coding standards have
31been waived. It does not pass cstyle. But, enough modifications were
32made so that the code does compile and lint cleanly.
33
34Some modifications have been made for use in the Solaris kernel:
351) compilation errors were corrected
362) lint complaints were fixed
373) a few utility interfaces were added
38	BZ2_bzCompressInitSize
39	BZ2_bzCompressReset
40	BZ2_bzDecompressReset
41	BZ2_bzErrorString
42
43
44Here is a complete list of changes made by Sun to the original 1.0.6
