Dear Members,

I often program CUDA applications and use Boost with comforts. And I
found Boost did not work fine when NVCC used a user-defined backend C++
compiler with the -ccbin option. The current implementation of Boost
only identifies GCC and Visual C++ that are the default backend
compilers of NVCC.

So I wrote a patch for other backend compilers. It ports the generic
identification routine of select_compiler_config.hpp to nvcc.hpp.

Best regards,
Ryohei
