my overlay doesn't compile

["pkoelle@gmail.com" <pkoelle@gmail.com>]

Hi list,

I played around to find out how overlays work but hit a brickwall when 
running make. The error is:
liboverlays.a(statover.o):(.data+0x58): undefined reference to 
'nestedgroup_initialize'
collect2: ld returned 1 exit status

nestedgroup_initialize is the initialization hook for my module 
(currently basically dynlist.c with some changes). I think I have added 
the relevant pieces to the build system (configure.in, 
servers/slapd/overlays/Makefile.in, include/portable.hin). Nevertheless, 
the linking error suggests there is still something missing.

thanks
 Paul
