Making Impala connection from Python on Windows (compiling lib SASL)

Time for a new war story...

1. Install Microsoft Visual C++ Compiler for Python 2.7 (see https://blogs.msdn.microsoft.com/pythonengineering/2016/04/11/unable-to-find-vcvarsall-bat/ for more background)
2. Copy stdint.h from http://msinttypes.googlecode.com/ (downloaded an archive) to "%USERPROFILE%\AppData\Local\Programs\Common\Microsoft\Visual C++ for Python\9.0\VC\include" (I'm running on Windows 2008 R2 x64). See http://deeplearning.net/software/theano/install_windows.html#visual-studio-and-cuda for more background
3. Create "%USERPROFILE%\AppData\Local\Programs\Common\Microsoft\Visual C++ for Python\9.0\VC\include\unistd.h"

   #ifndef _UNISTD_H
   #define _UNISTD_H    1
   
   /* Values for the second argument to access.
      These may be OR'd together.  */
   #define R_OK    4       /* Test for read permission.  */
   #define W_OK    2       /* Test for write permission.  */
   //#define   X_OK    1       /* execute permission - unsupported in windows*/
   #define F_OK    0       /* Test for existence.  */
   
   #define access _access
   #define dup2 _dup2
   #define execve _execve
   #define ftruncate _chsize
   #define unlink _unlink
   #define fileno _fileno
   #define getcwd _getcwd
   #define chdir _chdir
   #define isatty _isatty
   #define lseek _lseek
   
   #define ssize_t unsigned int
   
   #define STDIN_FILENO 0
   #define STDOUT_FILENO 1
   #define STDERR_FILENO 2
   
   char *getpass(const char *prompt)
   {    
       return "Hello World!";
   }
   
   
   #endif /* unistd.h  */
   

4. git clone https://github.com/cyrusimap/cyrus-sasl

5. Follow https://jira.mongodb.org/browse/CXX-645, specifically:
1. Use "VS2013 x64 Native Tools Command Prompt"
2. In cyrus-sasl\lib run

   nmake /f ntmakefile STATIC=no prefix=C:\sasl64

   . Note this uses /MD.
3. Run

   nmake /f ntmakefile prefix=C:\sasl64 STATIC=no install

   in cyrus-sasl\lib, cyrus-sasl\include, cyrus-sasl\win32\include 
4. Rename C:\sasl64\lib\libsasl.lib to C:\sasl64\lib\sasl2.lib 
6. Create requirements.txt

   impyla
   thrift_sasl
   pure-sasl
   

7. Create Makefile

   SCRIPTS_HOME=$(PYTHON_HOME)/Scripts
   PIP=$(SCRIPTS_HOME)/pip.exe
   
   pip-requirements:
    $(PIP) install -r requirements.txt --global-option=build_ext \
                   --global-option=-IC:\\sasl64\\include \
                   --global-option=-LC:\\sasl64\\lib

8. Run 'make pip-requirements PYTHON_HOME=C:\\Anaconda2-4.0.0'
