exp_dist.adb (Build_From_Any_Call): For a subtype that is a generic actual type...

2009-04-16  Thomas Quinot  <quinot@adacore.com>

	* exp_dist.adb (Build_From_Any_Call): For a subtype that is a generic
	actual type, use the base type to build the To_Any function.
	(Build_From_Any_Function): Remove junk, useless subtype conversion.

2009-04-16  Thomas Quinot  <quinot@adacore.com>

	* exp_ch9.adb, exp_code.adb, tbuild.adb, sem_case.adb,
	restrict.adb: Minor code reorganization (use
	Add_{Char,Str}_To_Name_Buffer instead of inlining it by hand).
