That test was introduced in configure.in 1.9, on 1994/11/03. It might
well be that autoconf did not support that test at that time.

I think it is generally the right thing to define _XOPEN_SOURCE on
Unix, providing a negative list of systems that cannot support this
setting (or preferably solving whatever problems remain).

I'd put an (unconditional) AC_DEFINE into configure.in early on; it
*should* go into confdefs.h as configure proceeds, and thus be active
when other tests are performed.
