Changes in version 1.1:

Support for decompression of lzma-alone (.lzma) files has been added.

Match length limit set by options -1 to -8 has been reduced to extend
range of use towards gzip. Lower numbers now compress less but faster.
(-1 now takes 43% less time for only 20% larger compressed size).

(Note that the bidimensional parameter space of LZMA can't be mapped to
a linear scale optimal for all files. If your files are large, very
repetitive, etc, you may need to use the --match-length and
--dictionary-size options directly to achieve optimal performance).

Code has been converted to "C89 + long long". A C99 compiler is no more
needed.
