APAR status

• Closed as program error.

Error description

• The header file omp.h in fileset xlsmp.rte contains the
  following enum:
  
  typedef enum omp_sched {
   omp_sched_unknown= 0,/* not a valid type */
  
    /* following 4 schedule kinds are defined in Open 3.0
  Specification */
    omp_sched_static= 1,/* GUIDED scheduling type */
    omp_sched_dynamic= 2,/* DYNAMIC scheduling type */
    omp_sched_guided= 3,/* STATIC scheduling type */
    omp_sched_auto= 4,/* AUTO scheduling type */
  
    ibm_sched_affinity= 1000,/* AFFINITY scheduling type. This is
  an IBM extension. */
  
  } omp_sched_t;
  
  The comma at the end of the ibm_sched_affinity element does not
  conform with the stdc89 language level, and will produce an
  error for users compiling with -qlanglvl=stdc89.
  

Local fix

• - Manually delete the comma from omp.h
  - Compile with a later language level (i.e. -qlanglvl=stdc99)
  

Problem summary

• PROBLEM DESCRIPTION:
  The XLSMP runtime V1.8.0.0 introduced new content into the
  omp.h header file contained in /usr/include/.  This new version
  of omp.h contains the following enum:
  
  typedef enum omp_sched {
  omp_sched_unknown= 0,/* not a valid type */
  
  /* following 4 schedule kinds are defined in Open 3.0
  Specification */
  omp_sched_static= 1,/* GUIDED scheduling type */
  omp_sched_dynamic= 2,/* DYNAMIC scheduling type */
  omp_sched_guided= 3,/* STATIC scheduling type */
  omp_sched_auto= 4,/* AUTO scheduling type */
  
  ibm_sched_affinity= 1000,/* AFFINITY scheduling type. This is
  an IBM extension. */
  
  } omp_sched_t;
  
  For some time, AIX headers, such as omp.h, followed the c89
  standard.  Newer versions of AIX no longer completely follow
  the c89 standard, and have introduced commas at the end of the
  lists in enum types.  Users compiling with the c89 standard
  will experience a syntax error caused by this comma:
  
  ''/usr/include/omp.h'', line 50.27: 1506-275 (S) Unexpected
  text ',' encountered.
  

Problem conclusion

• Removed the last comma in the enum in omp.h .
  

Temporary fix
