I realize I need to switch to cross gcc-4.9.x, but I'm so far along with
4.6 already that I wanted to try this first, as it is the last remaining
obstacle. It didn't work:

In file included from 
/home/greg/msw/i686-w64-mingw32/include/wx/pdfdocument.h:25:0,
                 from /home/greg/msw/i686-w64-mingw32/include/wx/pdfdc.h:21,
                 from /home/greg/src/lmi/group_quote_pdf_gen_wx.cpp:57:
/home/greg/msw/i686-w64-mingw32/include/wx/pdfarraytypes.h:28:110: error: 
invoking macro WX_DEFINE_SORTED_USER_EXPORTED_TYPEARRAY argument 4: empty macro 
arguments are undefined in ISO C90 and ISO C++98

even though I certainly did change it:

/home/greg/build/lmi-msw[0]$grep PdfSorted 
/home/greg/msw/i686-w64-mingw32/include/wx/pdfarraytypes.h
//WX_DEFINE_SORTED_USER_EXPORTED_ARRAY_INT(int, wxPdfSortedArrayInt, 
WXDLLIMPEXP_PDFDOC);
WX_DEFINE_SORTED_USER_EXPORTED_ARRAY_INT(int, wxPdfSortedArrayInt, 
wxEMPTY_PARAMETER_VALUE WXDLLIMPEXP_PDFDOC);

I tried rerunning 'configure' with various '-std=' options added to
CXXFLAGS, just in case I might quickly find a magical answer; that
was fruitless. But I did see something that seems interesting enough
to mention--this error message:
  configure: error: Please configure wxWidgets using --enable-std_string.
appears with c++11, g++11, and g++03, but not with c++03.

Oh, and BTW, I keep seeing this when I configure lmi:
  configure: WARNING: using cross tools not prefixed with host triplet

Fixed 20160122T1530Z, revision 6489.
