      With the latest Python 3.8.10 under cygwin the following fails:

      >>> import os
>>> os.listxattr('.')
Traceback (most recent call last):
  File "<stdin>", line 1, in < module>
AttributeError: module 'os' has no attribute 'listxattr'

      /usr/include/attr/xattr.h declares the corresponding library functions, so something must be wrong in the configuration/compilation of python itself.

      This is listed in the docs as a linux-only feature:

      Perhaps it could be supported under cygwin though without too much effort? Most likely just a configuration fix?

      After all, cygwin is a sort of linux ...

      Hey @iritkatriel.

      Since you're core developer... any chance that you could perhaps review my proposed PR for this? 😇
      Would be awesome.

      Thanks,
      Philippe

      Thanks for the fix!

      For reference: Cygwin is unsupported platform, meaning we don't test it. The feature may break in the future.
