    NMAKE : fatal error U1077: '"C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\BIN\cl.EXE"' : return code '0x2'

    I look at ruby.h (106) and see this:

    typedef char ruby_check_sizeof_voidp[SIZEOF_VOIDP == sizeof(void*) ? 1 : -1];

    How can we fix this? Any of you successfully compile ruby 2.4.1 on Windows?
