undefined reference when linking a dll

[Sam Steingold]

Hi,
I get this error on windows:

./clisp-link: failed in /cygdrive/c/sds/src/clisp/current/build-mingw-g/full
make: *** [full] Error 1

$ nm libgnu.a | grep rpl_setsockopt
000000c8 T _rpl_setsockopt
$ nm lisp.exe | grep rpl_setsockopt
0055dfbc T _rpl_setsockopt
$ grep rpl_setsockopt lisp.def
        lisp.exe._rpl_setsockopt

this is despite "lisp.exe._rpl_setsockopt" et al being present in
lisp.def IMPORTS section.
note that all the other (non-gnulib) symbols in lisp.exe mentioned in
rawsock.o link just fine, e.g.:

asciz_to_string
$ nm rawsock/rawsock.o | grep asciz_to_string
         U __imp__asciz_to_string
$ nm lisp.exe | grep asciz_to_string
0044731c T _asciz_to_string
$ grep asciz_to_string lisp.def
        lisp.exe.asciz_to_string

and there are no errors about asciz_to_string.

this is because asciz_to_string is declared with __declspec(dllexport)
where it is defined.
there seems to be no way to add such a declaration to the rpl_setsockopt
et al.

if, instead, I add libgnu.a to the command line, I get

libgnu.a(sendto.o): In function `rpl_sendto':
/cygdrive/c/sds/src/clisp/current/build-mingw-g/gllib/../../src/gllib/sendto.c:36:
 undefined reference to address@hidden'

so, how do I create a dll which refers to the gnulib functionality?
