* MNT: always require va_start to have two arguments python/cpython#93215 chance CPython to always use the 2-input version of va_start and dropped defining HAVE_STDARG_PROTOTYPES. This resulted in the 1-argument version being used when compiling cython source which fails This makes cython also always use the 2-argument version. * Remove blank line * FIX: version gate 2-argument va_start checking to py311
