PK75940: CCN3304 IN APPLICATION CODE DUE TO NON-STANDARD PROTOTYPES IN STDIO.H

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• When a application including stdio.h and using external variable
  optind is compiled with STRICT, FLAG(I) options results in
  CCN3304 information message. For example
  CCN3304 No function prototype given for "__Opnd".
  
  Similar issue is also there with other prototypes that do not
  satisfy strict standard for prototypes (__Oprg() etc).
  
  __Opnd() is declared as
  int *__Opnd();
  And it should have been
  int *__Opnd(void);
  
  The -V options also makes these messages to Warning level.
  

Local fix

• Ignore. This does not stop from compiler generating the object
  or cause any link errors.
  

Problem summary

• ****************************************************************
  * USERS AFFECTED: C applications that include either stdio.h   *
  *                 or unistd.h headers in order to use any of   *
  *                 the following external variables:            *
  *                   optarg, optind, opterr, or optopt          *
  *                 as shared variables (by defining either      *
  *                 _SHARE_EXT_VARS or _SHR_OPTARG,              *
  *                 _SHR_OPTIND, _SHR_OPTERR or _SHR_OPTOPT      *

Problem conclusion

• The prototypes for these variables are now defined with a void
  pointer to avoid this message.
