APAR status

• Closed as program error.

Error description

• Compiling the following codes:
  
  int stat (char __file, int __buf) _Pragma("map(stat,
  \"stat64\")");
  int stat64 (char __file, char __buf);
  
  causes unexpected informational message:
  
  ... 1506-377 (I) The type "int" of parameter 2 differs from the
  previous type "char"...
  

Local fix

• Use -qsuppress=1506-377
  

Problem summary

• USERS AFFECTED:
  Users or pragma map who map a symbol to another with different
  type.
  
  PROBLEM DESCRIPTION:
  Compiler issues some info messages when symbols being mapped
  with pragma map do not have the same type.
  

Problem conclusion

• C++ does not check that the types are compatible with pragma
  map because it is the user's responsiblity to map a symbol to
  one with the same type. However, because this diagnostic may
  still be useful for some users, C will do type checking for
  pragma map only under -qinfo=gen.
  

Temporary fix
