[Bug libobjc/39465] libobjc does not find classes of DLLs

Any news? I even tried this now, which still produced an .a file:

../gcc-4.3.0-20080502/configure -v --prefix=/usr --libexecdir=/usr/lib \
--program-prefix=mingw32- --target=mingw32 --with-headers=/usr/mingw32/include
--disable-nls --enable-shared --enable-languages=objc
make configure-target-libobjc
make all-target-libobjc
make install-target-libobjc

Note the --enable-shared, which is _DEFINITELY_ being passed to configure
(quoting Makefile in builddir):

maybe-configure-target-libobjc: configure-target-libobjc
configure-target-libobjc: 
        @: $(MAKE); $(unstage)
        @r=`${PWD_COMMAND}`; export r; \
        s=`cd $(srcdir); ${PWD_COMMAND}`; export s; \
        echo "Checking multilib configuration for libobjc..."; \
        $(SHELL) $(srcdir)/mkinstalldirs $(TARGET_SUBDIR)/libobjc ; \
        $(CC_FOR_TARGET) --print-multi-lib >
$(TARGET_SUBDIR)/libobjc/multilib.tmp 2> /dev/null ; \
        if test -r $(TARGET_SUBDIR)/libobjc/multilib.out; then \
          if cmp -s $(TARGET_SUBDIR)/libobjc/multilib.tmp
$(TARGET_SUBDIR)/libobjc/multilib.out; then \
            rm -f $(TARGET_SUBDIR)/libobjc/multilib.tmp; \
          else \
            rm -f $(TARGET_SUBDIR)/libobjc/Makefile; \
            mv $(TARGET_SUBDIR)/libobjc/multilib.tmp
$(TARGET_SUBDIR)/libobjc/multilib.out; \
          fi; \
        else \
          mv $(TARGET_SUBDIR)/libobjc/multilib.tmp
$(TARGET_SUBDIR)/libobjc/multilib.out; \
        fi; \
        test ! -f $(TARGET_SUBDIR)/libobjc/Makefile || exit 0; \
        $(SHELL) $(srcdir)/mkinstalldirs $(TARGET_SUBDIR)/libobjc ; \
        $(NORMAL_TARGET_EXPORTS) \
        echo Configuring in $(TARGET_SUBDIR)/libobjc; \
        cd "$(TARGET_SUBDIR)/libobjc" || exit 1; \
        case $(srcdir) in \
          /* | [A-Za-z]:[\\/]*) topdir=$(srcdir) ;; \
          *) topdir=`echo $(TARGET_SUBDIR)/libobjc/ | \
                sed -e 's,\./,,g' -e 's,[^/]*/,../,g' `$(srcdir) ;; \
        esac; \
        srcdiroption="--srcdir=$${topdir}/libobjc"; \
        libsrcdir="$$s/libobjc"; \
        rm -f no-such-file || : ; \
        CONFIG_SITE=no-such-file $(SHELL) $${libsrcdir}/configure \
          $(TARGET_CONFIGARGS) --build=${build_alias} --host=${target_alias} \
          --target=${target_alias} $${srcdiroption}  \
          || exit 1

And TARGET_CONFIGARS is:

TARGET_CONFIGARGS = --cache-file=./config.cache --enable-multilib
--with-cross-host=i686-pc-linux-gnu '-v' '--prefix=/usr'
'--libexecdir=/usr/lib' '--with-headers=/usr/mingw32/include' '--disable-nls'
'--enable-shared' '--enable-languages=c,objc'
--program-transform-name='s,^,mingw32-,'
--with-target-subdir="$(TARGET_SUBDIR)"

As you can see, --enable-shared is listed there, so libobjc's configure is
simply ignoring --enable-shared it seems.
