ldexpl() was added in NetBSD 7 (released Sept 2015).  NetBSD 6 was released in
Oct 2012 and last had a point release in Sept 2014).  NetBSD 6 is still
supported by upstream per https://www.netbsd.org/releases/formal.html#history

NetBSD 8 is in beta and no release date has been announced yet.  I would expect
NetBSD 6 support to be dropped when NetBSD 8 comes out.

Do we need to support NetBSD 6 given it's age and lack of complete c99 support?

Thanks,
