[lmi] wx-2.9.2: should '--disable-threads' force '--disable-fswatcher'?

[Greg Chicares]

While building this tarball:
  ftp://ftp.wxwidgets.org/pub/Daily_HEAD/files/wx-all-2010-11-06.tar.gz

../configure --prefix=/opt/lmi/local --build=i686-pc-cygwin 
--host=i686-pc-mingw32 \
[...] --disable-threads [...] && make && make install
[...]
In file included from ../include/wx/chkconf.h:1138,
                 from ../include/wx/platform.h:711,
                 from ../include/wx/defs.h:26,
                 from ../include/wx/vector.h:15,
                 from ../src/stc/scintilla/src/Selection.h:134,
                 from ../src/stc/scintilla/src/Editor.cxx:41:
../include/wx/msw/chkconf.h:408:13: #error "wxFileSystemWatcher requires 
wxThread under MSW"

If I add '--disable-fswatcher', then that problem does not occur.
Should '--disable-threads' force '--disable-fswatcher'? (I haven't
tried this with any wx version later than 2010-11-06.)
