--- Comment #8 from jordan triplesquarednine@gmail.com 2013-04-09 22:18:47 CDT --- So, the bug report i linked to, does allow wine64 to work - but obviously, that isn't a permanent solution.
so these errors/warnings in my report aren't the cause of breakage on gcc-4.8.0 - but there is breakage with wine64 for sure.
i had thought maybe signal_x86_64.c throwing warnings was linked to the problem, but maybe not (?).
