Christian Heimes added the comment:
> The main reason for two different hash algorithms was missing support for
64bit integer types. Python 3.4 was targeting platforms that had no 64bit
integer support at all (IIRC SPARC). Nowaday Python requires 64bit ints to
compile.

deprecated it now and remove it in 3.7.

Python 3.5.0 doesn't compile if the compiler doesn't support 64 signed
integer: see pytime.h ;-)

Are you aware of platforms still using FVN2?

I'm also in favor of deprecating it. Maybe use #warning in C to log a
deprecation warning.
