Doing so makes the Visual C compiler much less accepting of ill formed code, which will improve code quality on Windows in the future.

This got a bit messy. In hindsight it would probably have been better to leave this closed and open a new bug. But what's done is done, let's not mess around any more at this point.

If all other places where `permissive-` failed are fixed, then I think it is okay to include the flag in this PR. Otherwise, you cannot do that. As a general rule, changing compiler options is best done in a separate patch, to differentiate any potential bad effect from actual code changes. However, in this case, I don't think the flag will cause any differences in the generated code, only in what syntax the compiler accepts, so I guess it is fine.
