	* gnatls.adb: Get the target parameters only if -nostdinc was
	not specified.

2014-07-16  Ed Schonberg  <schonberg@adacore.com>

	* checks.adb (Insert_Valid_Check): If the expression is a packed
	component of a modular type of the right size the data is always
	valid. This os particularly useful if the component is part of
	a volatile variable.

	* gnat_rm.texi, sinfo.ads, freeze.adb, exp_aggr.adb: Minor reformatting
