Warnings are comes from it. But errors are not.

httptools/parser/parser.c:8187:5: error: lvalue required as increment operand
 ++Py_REFCNT(o);
 ^~
 httptools/parser/parser.c:8189:5: error: lvalue required as decrement operand
 --Py_REFCNT(o);
 ^~

Try regenerating parser.c with newest Cython release. It will solve all warnings and errors.
