	* a-dirval-mingw.adb: Remove some characters from Invalid_Character set.

2015-10-27  Ed Schonberg  <schonberg@adacore.com>

	* exp_ch6.adb (Rewrite_Function_Call_For_C): Use a named
	associaion for the added actual in the call because previous
	actuals may also have been given by explicit associations.
	* lib-xref.adb: Minor style fixes.
