Not a good sign, but can't help without more info, sorry.

What does `objdump -p lk.dll' show? Anything odd?

How about the following (I'm curious more than anything else):

  $ dlltool --export-all --output-def lk.def liblk.a
  $ c++ -shared -o OBJ.x86-pc-win32/lk.dll -Wl,--out-implib,liblkimp.a \
    lk.def liblk.a -L/usr/misc/lib -lgcimp

Same problem?

This is going to be one of those problems that's very hard to debug
without full testcase (preferably with sources), which is obviously 
awkward for proprietary apps.
