--- Comment #7 from Tom B tom@r.je --- Ok, looking again that may not be the case.
If I use wine 3.18 I cannot log in to windows Steam, it can't log in with "could not connect to the steam network". This is true if I use the Arch Linux wine package or build from source (Either the latest git master or the 3.18 tag). This is a separate issue but makes it difficult to test this bug.
To test reverting 1312c6642851d4a0c5de9a71c824800935f96691 above I used wine staging and just realised that the build script checks out a particular branch. undoing the reversion.
I'd rather not use staging as it adds an extra variable but as it stands this makes it very difficult to test as I can't seem to compile a version of wine that allows me to log in on Steam and have the commit reverted at the same time.
