You are correct, these are violations.  I haven't changed it because
it breaks the interface.

The change will be to protect the definitions of struct option, the
*_argument macros, and the extra prototypes using

	#ifdef _GNU_SOURCE


If every program which relies on the extensions uses as suggested
-D_GNU_SOURCE there should not be any problem.
