-dnl On glibc we need to define at least the '_XOPEN_SOURCE' level of features,
-dnl or wchar.h doesn't declare a prototype for wcwidth(). But if we only define
-dnl that level then db.h won't compile. So we define _GNU_SOURCE which turns

-dnl declared; if so they should have an entry added to this case statement.
-dnl NB that we must define this on the compiler command line, not in config.h,
