	* sysdep.c (__gnat_has_cap_sys_nice): If HAVE_CAPABILITY is defined,
	we include the proper header. Otherwise, we just declare the necessary
	things from the capabilities library. This is so we can build on
	machines without that library, while still enabling that library.
	At run time, we're using weak symbols, so __gnat_has_cap_sys_nice will
	simply return 0 if the library is not present, or not included
	in the link.

	* sem_ch3.adb (Analyze_Subtype_Declaration):
	Set Has_Delayed_Freeze on a subtype of an incomplete type.

2017-09-06  Pierre-Marie de Rodat  <derodat@adacore.com>

	* par_sco.adb (Extend_Statement_Sequence): When the accept statement
	has no parameter specification and no entry index, use the entry name
	as the end of the generated SCO statement.
