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().
Signed-off-by: Paul Gofman pgofman@codeweavers.com --- v2: - allow any space as terminator and add tests for that; - remove now duplicate inet_addr() tests from test_inet_pton (the main part of those didn't work due to missing brackets for '?' operator).

Hi,
While running your changed tests, I think I found new failures. Being a bot and all I'm not very good at pattern recognition, so I might be wrong, but could you please double-check?
Full results can be found at: https://testbot.winehq.org/JobDetails.pl?Key=109679

Eh... I added the whole loop for that which tests all the possible characters in the end of the string?

Ah, I see you did. I was expecting them to be added as part of the tests[] array, but that works too :-)
