-fno-strict-aliasing should only be the last resort when it's impossible to fix strict-aliasing rules and can be a huge penalty. Even if gcc prints out warnings about broken strict-aliasing rules, it's not sure that there are actual runtime issues.

Building latest head without this flag and "-fstrict-aliasing" enabled does not reveal any warnings, so it's fairly safe to remove this flag.
