package/python3/111-optional-decimal.patch

   1 Add an option to disable decimal
   2
   3 This patch replaces the existing --with-system-libmpdec option with a
   4 --with-libmpdec={system,builtin,none} option, which allows to tell
   5 Python whether we want to use the system libmpdec (already installed),
   6 the libmpdec builtin the Python sources, or no libmpdec at all.
