[issue29464] Specialize FASTCALL for functions with positional-only parameters

[Serhiy Storchaka]

Serhiy Storchaka added the comment:

I think you need to update Cython to a version that supports new FASTCALL call convention in 3.7. If the support of FASTCALL in Cython is optional try to disable it.
