Why not first try to search for the bug and report it to the GCC people ?
IMHO Wine has so much things to take care of that are more important than a GCC bug that the better way to handle this for now is to filter off that flag.
There're also other softwares which filter some flags, or that can't be build correctly with certainly flags. If you take the gentoo's ebuilds there are a lot of filter-flag commands to remove some flags (-fforce-addr for example make xine's build process merely fail).
