    Description

      Leaving variables uninitialized in certain cases helps to achieve top-notch performance. Sometimes compiler thinks that variable may be used uninitialized (whereas it may not) and emits a warning.

      To silence these warnings there is LINT_INIT() macro:

      #if defined(_lint) || defined(FORCE_INIT_OF_VARS) || \
          (defined(__GNUC__) && defined(__cplusplus))
      #define LINT_INIT(var) var= 0
      #else
      #define LINT_INIT(var)
      #endif

      It always emits "x= 0" for C++ code compiled with gcc. In fact this is a workaround for gcc bug, which was fixed 3 years ago.
