PI25812: KEYWORD __PTR32 QUALIFIER IS NOT ACCEPTED BY THE C++ COMPILER:

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• keyword __ptr32 qualifier is not accepted by the C++ compiler.
  Compiler Parser rules does not consider __ptr32 keyword in
  pointer typedefs. User is getting unexpected text error message.
  
  
  The keyword __ptr32 is a qualifier that can be applied to a
  pointer type to constrain its size to 32 bits. This language
  extension is provided to facilitate porting structures with
  pointer members from 31- to 64-bit mode. The qualifier is
  accepted and ignored in 31-bit mode.
  
  Unfortunately, this qualifier is not accepted by the C++
  compiler:
  
  --- a.C ---
  typedef char* MyCP;
  
  struct S {
     MyCP volatile d; // Works
     MyCP __ptr32 c; // Does not work
  };
  --- end a.C ---
  
  Run:
  xlC a.C
  
  Output:
  "./a.C", line 5.9: CCN5063 (S) The text "__ptr32" is unexpected.
  CCN0793(I) Compilation failed for file ./a.c.  Object file not
  created
  

Local fix

• Use __ptr32 qualifier on the underlying declaration
