Paul Gofman : ws2_32: Base inet_addr() implementation on musl.
Module: wine Branch: master Commit: 18230d23c599f1f5f9dd419dccc11c49117cc3b8 URL: https://source.winehq.org/git/wine.git/?a=commit;h=18230d23c599f1f5f9dd419dc... Author: Paul Gofman <pgofman(a)codeweavers.com> Date: Thu Mar 3 13:32:26 2022 +0300 ws2_32: Base inet_addr() implementation on musl. The imported algorithm is modified to match the tests. Fixes a regression introduced by commit 671cf16f773e5dafc7edbf7766aed9e52e4e7b56. Windows inet_addr() behaves basically the same as Unix inet_addr() which is different from inet_pton().
