pre-compile is failing with `aenum` package

The part of error log:
```
pypi_311_aenum_py3_none_any_e0dfaeea/site-packages/aenum/__pycache__/_py2.cpython-311.pyc
```

It seems that the wheel that I am using is https://files.pythonhosted.org/packages/d0/fa/ca0c66b388624ba9dbbf35aab3a9f326bfdf5e56a7237fe8f1b600da6864/aenum-3.1.15-py3-none-any.whl#sha256=e0dfaeea4c2bd362144b87377e2c61d91958c5ed0b4daf89cb6f45ae23af6288

The precompile config setting was set to `enabled` and I was using the latest `rules_python 1.3.0rc1` on a mac host.

One of the errors:
```

```

And the contents of this file are:
```from operator import div as _div_
from inspect import getargspec

def raise_with_traceback(exc, tb):
raise exc, None, tb

__all__ = ['_div_', 'getargspec', 'raise_with_traceback']
```

I understand that I can patch the wheel to exclude the file, but I am curious what the user is expected to do in this case.

Start by reproducing the failure with the reported precompile setting and inspect aenum/_py2.py alongside the precompiler entry point and python/private/python3 shown in the error. Determine the expected handling for this Python-2-only file, then verify that the package can be processed without the reported SyntaxError and document or test the resulting behavior.
