Changes in version 0.8:

File diagnostics have been reformatted as 'PROGRAM: FILE: MESSAGE'.

In case of error in a numerical argument to a command line option, lunzip
now shows the name of the option and the range of valid values.

Diagnostics caused by invalid arguments to command-line options now show the
argument and the name of the option.

The option '-o, --output' now preserves dates, permissions, and ownership of
the file, when decompressing exactly one file.

The variable MAKEINFO has been added to configure and Makefile.in.

It has been documented in INSTALL that when choosing a C standard, the POSIX
features need to be enabled explicitly:
  ./configure CFLAGS+='--std=c99 -D_XOPEN_SOURCE=500'
