Indeed.  But that's not the entire problem.  What does

  #define _XOPEN_SOURCE

mean?  GLibc maps it to 

 #define _POSIX_C_SOURCE 2

nd it also covers the case that _XOPEN_SOURCE is set to 500 by
setting _POSIX_C_SOURCE to 199506L (that's SUSv2 right?)

We should do the same, perhaps.  WOuld you mind to prepare a patch?


Thanks,
