[Wine] applying a patch (select-dup.diff) to wine to fix TF2

[RedWagon]

I really feel like a n00b posting this, but I can't for the life of me find how to apply this patch.  http://bugs.winehq.org/attachment.cgi?id=21763&action=edit
One of the Steam updates broke TF2, and according to the comments in the bug tracker this should fix it.  I just have idea what to do with the file.  Also, my wine setup isn't like most peoples.  I compile wine from source and run it from the source directory so I can use multiple versions at the same time.  I don't need specific instructions for my setup, just generic wine instructions and whether or not I need to apply it to each source directory, or the directory with drive_c and stuff.
