xlunzip-0.10/main.c:530:9: style: Obsolescent function 'utime' called. It is recommended to use 'utimensat' instead. [prohibitedutimeCalled]
xlunzip-0.10/main.c:578:20: style: Parameter 'buf' can be declared as pointer to const. However it seems that 'flush' is a callback function, if 'buf' is declared with const you might also need to cast function pointer(s). [constParameterCallback]
xlunzip-0.10/main.c:620:52: note: You might need to cast the function pointer here
