Cygwin NEWS:

 * Fixed a HP-UX 11 build issue with Itanium in ILP32 mode.
 * Updated the configure system.

LZO is a data compression library which is suitable for data de-/compression in real-time.
This means it favours speed over compression ratio.

LZO implements a number of algorithms with the following features:

 * Decompression is simple and *very* fast.
 * Requires no memory for decompression.
 * Compression is pretty fast.
 * Requires 64 kB of memory for compression.
 * Allows you to dial up extra compression at a speed cost in the compressor. The speed of the decompressor is not reduced.
 * Includes compression levels for generating pre-compressed data which achieve a quite competitive compression ratio.
 * There is also a compression level which needs only 8 kB for compression.
 * Algorithm is thread safe.
 * Algorithm is lossless.

LZO supports overlapping compression and in-place decompression.
