where N is the number of data word bits supported by the compiler and/or target environment. Note that the most negative value, -2^(N-1), is not included in the supported range since many compilers do not always correctly handle this value.

Example Usage

          #define  CFG_VAL           -1
           
          #if     (DEF_CHK_VAL_MIN(CFG_VAL, 0u) != DEF_OK)  /* Signed CFG_VAL NOT promoted to unsigned. */
          #error  "CFG_VAL must be >= 0"
          #endif
