I have checked this in:

*** tab-complete.c      2001/06/11 22:12:48     1.33
--- tab-complete.c      2001/06/20 18:37:09
***************
*** 62,67 ****
--- 62,70 ----
 #ifdef HAVE_RL_FILENAME_COMPLETION_FUNCTION #define filename_completion_function rl_filename_completion_function
+ #else
+ /* missing in some header files */
+ extern char *filename_completion_function(); #endif
 #ifdef HAVE_RL_COMPLETION_MATCHES

I hope it still works for both of you. ;-)
