Are there any machines left, that anyone would want to compile
anything on, that _doesn't_ have str(r)chr?

I'd recommend assuming C89 for your project, and stop worrying about
pre-C89 issues.  If you know of a platform that lack str(r)chr,
implement them as a module and contribute it.  I think the gnulib
maintainers would approve.

Not speaking for the gnulib maintainers,
