Could you improve t1ha for compile with Visual C++ 9.0? #6

Closed Slach closed 7 years ago

Slach commented 7 years ago

i use python extension for some my projects https://github.com/flier/pyfasthash/issues/8 your great t1ha hash function included into https://github.com/rurban/smhasher/issues/30 package

and after i change target platoform to x64 t1ha.c can't compile under VC++ 9.0, but he required for Python2.7 compilation ;(

please, could you help me resolve following errors?

 t1ha.c
    It is recommended to use Visual Studio 2015 (MSC 19.0) or newer.
