  I once wrote about this problem :

  if the DLL is not loaded at its default address the
.reloc section 
 is by default before the .stab section but it is only inserted in
the second call to cygwin ld ! This causes wrong offsets for the
stabs relocation which typically can be inside the .reloc section itself !!

 I didn't get any answer at that time.

Apparently Microsoft linker knows about this potential problem
and gives a warning out !
