#glibc FAQ
#	"_GNU_SOURCE:  glibc does not make the GNU extensions available 
#	automatically.  If a program depends on the GNU extensions or some other
#	non-standard functionality, it is necessary to compile it with the C 
#	compiler option -D_GNU_SOURCE, or better to put #define _GNU_SOURCE at
#	the beginning of your source files, before any C library header files 
#	are included.  This difference normally manifests itself in the form
#	of missing prototypes and/or data type definitions.  Thus, if you get
#	such errors, the first thing you should do is try defining _GNU_SOURCE
#	and see if that makes the problem go away."
