Mmm...  I knew defining _XOPEN_SOURCE might bring issues.

The problem here is that defining it disables all GNU extensions which
people are used to see automatically enabled on Linux.  That probably
happens much more often that people with an environment where
_XOPEN_SOURCE is not enabled, so I dropped the definition of
_XOPEN_SOURCE, and will document instead.
