Hello
I tried to build wxWidgets-3.0.0 on Cygwin.
For Cygwin x86, the build was successful.
However, on Cygwin x86_64, the build failed at compling a cpp source file (src/common/appbase.cpp).
./include/wx/filename.h: In static member function 'static wxUniChar wxFileName::GetPathSeparator(wxPathFormat)':
./include/wx/filename.h:473:43: error: ambiguous overload for 'operator[]' (operand types are 'wxString' and 'unsigned int')
{ return GetPathSeparators(format)[0u]; }
The code "(format)[0u]" seemed to be accepted g++-4.8.2 on Cygwin x86_64.
What the difference of g++ between that of Cygwin x86 and that of Cygwin x86_64?
Regards
Tatsuro

wxWidgets requires several patches to build and/or run correctly on
Cygwin/X. I haven't looked at 3.0 yet, but for 2.8 this issue is fixed
in my 2.8.12-cygwin64.patch:

With your patch, I could build WxGTK-2.8.12. I can build gnuplot with the wxt terminal.
That is really I want to execute.
Thanks a lot!
