i checked all three cases:
 	1)
 		/* #define _GNU_SOURCE 1 /**/
 		#define _POSIX_C_SOURCE 200809L
 	2)
 		/* #define _GNU_SOURCE 1 /**/
 		/* #define _POSIX_C_SOURCE 200809L /**/
 	3)
 		#define _GNU_SOURCE 1
 		/* #define _POSIX_C_SOURCE 200809L /**/

cases 2 and 3 built patchlevel 1.5246 with no problem.  so, indeed,
removing _POSIX_C_SOURCE does help.  thank you very much for pinpointing
the search.

perhaps some directive such as the following might be sufficiently
restrictive to handle OS X and not interfere with other OS
installations on apple hardware:

#if !defined(__APPLE__) && !defined(__APPLE_CC__)
#define _POSIX_C_SOURCE 200809L
#endif
