The system headers on aix ps/2 have inconsistent definitions for:
size_t, ptrdiff_t and wchar_t.  And they are not protected against
redefinition.

Here is for example how you need to modify your /usr/include/stddef.h:

   ...
   #ifndef _PTRDIFF_T
   #define _PTRDIFF_T
   typedef int ptrdiff_t;
   #endif
   #ifndef _SIZE_T
   #define _SIZE_T
   typedef unsigned int size_t;
   #endif
   ...
   /*
    * MBCS typedefs 
    */
   #ifndef _WCHAR_T
   #define _WCHAR_T
   typedef unsigned long	wchar_t;	/* wide character */
   #endif
   
You need to to the same sort of thing for stdio.h, sys/types.h and stdlib.h.
