Changes in version 1.14: The option '--empty-error', which forces exit status 2 if any empty member is found, has been added. The option '--marking-error', which forces exit status 2 if the first LZMA byte is non-zero in any member, has been added. File diagnostics have been reformatted as 'PROGRAM: FILE: MESSAGE'. 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 option '-o, --output' now creates missing intermediate directories when writing to a 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'
