If you look at libtool.m4, wherever this is (reading it off the web):
cygwin*)
# _LT_AC_TAGVAR(hardcode_libdir_flag_spec, $1) is actually meaningless,
# as there is no search path for DLLs.
_LT_AC_TAGVAR(hardcode_libdir_flag_spec, $1)='-L$libdir'
_LT_AC_TAGVAR(always_export_symbols, $1)=no
if $LD --help 2>&1 | egrep 'auto-import' > /dev/null; then
_LT_AC_TAGVAR(archive_cmds, $1)='$CC -shared -nostdlib $predep_objects $libobjs

You see that, for mingw, it needs to be fixed and I propose that
someone *TEST* taking the cygwin implementation and moving down to
where mingw is, *and* removing the $predep_objects, like this:
mingw* )
_LT_AC_TAGVAR(hardcode_libdir_flag_spec, $1)='-L$libdir'
_LT_AC_TAGVAR(always_export_symbols, $1)=no
if $LD --help 2>&1 | egrep 'auto-import' > /dev/null; then
_LT_AC_TAGVAR(archive_cmds, $1)='$CC -shared -nostdlib $libobjs $deplibs
$postdep_objects $compiler_flags -o $output_objdir/$soname
${wl}--image-base=0x10000000 ${wl}--out-implib,$lib'
_LT_AC_TAGVAR(archive_expsym_cmds, $1)='$CC -shared -nostdlib $libobjs $deplibs
$postdep_objects $compiler_flags -o $output_objdir/$soname ${wl}-retain-symbols-file
$wl$export_symbols ${wl}--out-implib,$lib'
else
_LT_AC_TAGVAR(ld_shlibs, $1)=no
fi
;;
pw32* )
# FIXME: insert proper C++ library support
_LT_AC_TAGVAR(ld_shlibs, $1)=no

What is the conventional wisdom on this?
