I suppose the error comes from the fact that you are using the 32bit compiler. *i686*-w64-mingw32-gcc.exe is 32bit, try with x86_64-w64-mingw32-gcc.exe
If CC is set correctly, cgo should use that. If you are worried that gcc.exe is being used, temporarily move gcc.exe where cgo can't find it and try to compile again.
