Would you mind updating the patch so that if _POSIX_VERSION is defined
and >= 200809L, then index() and friends are _not_ declared?  That is:

#if !defined __STRICT_ANSI && _POSIX_VERSION < 200809L

I don't mind them being declared when using all available extensions,
but I don't want them polluting the namespace when trying to compile a
POSIX 2008 conforming application (index is the worst offender, as I
like using that identifier in my code for other purposes).
