Following up on this, I noticed that slapd's build process is quite 
broken, resulting in an invalidly formatted executable.  The working 
method to create a linkable EXE is to just link it with 
-Wl,--export-all-symbols,--out-implib,libfoo.a, then link other modules 
with -Wl,path/to/libfoo.a.  (Relying on -L flags for in-tree paths isn't 
always a good idea with libtool.)

I took the liberty of fixing up the build of slapd both with and without 
modular backends/overlays.  The patch and modified cygport(3) are in 
Ports git:
