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'
