Using the CHECKOUT Option for C Headers

The IBM C compiler products on the System/390 platform have a CHECKOUT option that provides warnings for dubious code and provides informational messages as warnings. All C header files must compile cleanly with the CHECKOUT option, while all C language executable code must compile cleanly without the CHECKOUT option.

External headers must compile with RC=0 with the CHECKOUT option.

Use the following parameters to compile with the CHECKOUT option:

     CHECKOUT(NOPPC)
 
     This works for the IBM SAA AD/Cycle C/370 Compiler.
Note:
Depending on the compiler, the parameters can change at a future time.
