Changes in version 0.4:

The lzip_decompress module has been updated to version 4.18.1-2.

A harmless warning on 32 bit systems has been fixed.

Large amounts of trailing zeros are now skipped more efficiently when
decompressing or testing in place.

Errors are now also checked when closing the input file.

It has been documented in INSTALL the use of '-D __USE_MINGW_ANSI_STDIO'
when compiling on MinGW.
