Problem solved
I created unistd.h from the most popular answer here
http://stackoverflow.com/questions/341817/is-there-a-replacement-for-unistd-h-for-windows-visual-c

and downloaded getopt.h and getopt.c from here
http://www.codeproject.com/Articles/157001/Full-getopt-Port-for-Unicode-and-Multibyte-Microso

and I put them into C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\include\

if that error showed up to you "c:\users\batman\anaconda3\envs\py35\include\pyconfig.h(193): error C2632: '__int
64' followed by 'int' is illegal
c:\users\batman\anaconda3\envs\py35\include\pyconfig.h(193): warning C4091: 'typ
edef ': ignored on left of '__int64' when no variable is declared"

CHANGE line 193 in pyconfig.h to typedef signed __int64 int64_t;
cuz you can't leave the compiler to decide the default signed or unsigned datatype
