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.
