Wine 1.1.41 is out since 2010-03-19 and not yet in portage.
Well, the renamed ebuid seems to work fine. However, since a few versions back, I've been experiencing strange hangs, if internal debugger gets invoked - that is stack trace gets printed, but wine doesn't exits. I've got a feeling, that their "fix" to the _FORTIFY_SOURCE problem may play a role here.
now in the tree; thanks for the heads up
