	* sem_util.adb: Minor typo correction.

2014-07-18  Ben Brosgol  <brosgol@adacore.com>

	* gnat_rm.texi: Complete previous change.

2014-07-18  Pascal Obry  <obry@adacore.com>

	* s-fileio.adb: Minor style fix.

2014-07-18  Ed Schonberg  <schonberg@adacore.com>

	* sem_ch13.adb (Analyze_Aspect_Specifications): Detect improper
	specification of stream attributes for subtypes that are not
	first subtypes, to prevent malformed rep_item chains in the case
	of such illegal specifications for discriminated private subtypes.
	(Check_Overloaded_Name): Verify that the name is an entity name
	before other checks.

2014-07-18  Pascal Obry  <obry@adacore.com>

	* adaint.c (__gnat_fputwc) Do not disable on cross-build.
