Okay, so Simon was exactly right in his guess about what you were doing 
wrong...    Excellent intuition, Simon!

Here's a link to the Information Center page:
http://publib.boulder.ibm.com/infocenter/iseries/v5r4/topic/apis/renamefs.htm

the very first words on the page:

   The rename() function can be defined to be either
   Qp0lRenameUnlink() or Qp0lRenameKeep(), depending upon the
   definitions of the _POSIX_SOURCE and _POSIX1_SOURCE macros . . .

You _are_ using the API!  (Or trying to.)   What did you think you were 
calling?!

Anyway, it appears Sharon has already posted a prototype you can use... 
so your problem should be solved...    But, FWIW, here's what I have 
coded in my IFSIO_H copy book:

      /if defined(RENAMEUNLINK)
     D rename          PR            10I 0 ExtProc('Qp0lRenameUnlink')
     D   old                           *   Value options(*string)
     D   new                           *   Value options(*string)
      /else
     D rename          PR            10I 0 ExtProc('Qp0lRenameKeep')
     D   old                           *   Value options(*string)
     D   new                           *   Value options(*string)
      /endif
