setup.py install fails

[ursomniac]

numpyconfig.h:33:10: error:
"unknown architecture"
#error "unknown architecture"
^

There are additional warnings.
I'm trying to install under MacOS (10.14.6) under pipenv (Python 3.9).
So, platform.system() == 'Darwin' --- this SHOULD set -arch to x86_64 (line 21 in your setup.py) but when it gets to

#ifdef __x86_64
    #define NPY_SIZEOF_LONGDOUBLE         16
    #define NPY_SIZEOF_COMPLEX_LONGDOUBLE 32
#elif defined(__arm64__)
    #define NPY_SIZEOF_LONGDOUBLE         8
    #define NPY_SIZEOF_COMPLEX_LONGDOUBLE 16
#else
    #error "unknown architecture"

it's bottoming out.

Please advise.

Could you try parameters from https://github.com/thespacedoctor/HMpTy/blob/master/setup.py#L46, if it helps? Possibly create PR if it is working. Thanks!
