Unable to Build pandas with Py38, macOS (clang?) and Cython>0.29.13 (tp_print warning)
Dedicated issue for @jbrockmendel callout in https://github.com/pandas-dev/pandas/issues/30609#issuecomment-605373212

I opened an issue on the Cython side as well https://github.com/cython/cython/issues/3474

There's a rabbit hole of conversation with this going back to CPython . This may just be a temporary issue for Py38, so one "workaround" could be to just add `-Wno-deprecated-declaration` when these particular combination of things is detected, though of course an actual fix would be ideal
