I have had success compiling the vector_add test code with Visual Studio v14.0 (aka 2015)

1) change Project vector_add properties Additional Depenancies "OpenCL.lib;legacy_stdio_definitions.lib;%(AdditionalDependencies)"

2) change the main.cpp program, at top of file after includes

FILE _iob[] = { *stdin, *stdout, *stderr };

extern "C" FILE * __cdecl __iob_func(void) { return _iob; }

extern "C" void __imp__set_output_format(void) {};

This may break other things, but the vector_add test works with these changes. (refs https://stackoverflow.com/questions/31242820 , https://stackoverflow.com/questions/30412951 )
