Thanks, but I can't find it. I found apr_strmatch in apr-util, but
that doesn't do regex, it just matches a fixed string (which would
also be useful (it actually covers my concrete use-case), but it's not
-F). Maybe I'm overlooking something.

If it's not in apr(-util) or some other dependency we already have,
how about PCRE (www.pcre.org) ?
