wxWidgets/include/wx/strconv.h
Julian Smart 65e5084827 Added wxTB_NODIVIDER and wxTB_NOALIGN so native Windows toolbar can
used in FL.
Adjusted Windows toolbar height for wxTB_NODIVIDER style.
Removed some false memory leak reporting from fontmap.cpp, mimecmn.cpp,
strconv.cpp.
Added and used MapBitmap function in newbmpbtn.cpp so the right
colours are used under Windows.
<controversial>Added iniconf.cpp to WIN32 compilation</conroversial>
