2009-11-30  Vincent Celier  <celier@adacore.com>

	* prj-makr.adb (Source_Files): New hash table to keep track of source
	file names.
	(Finalize): Avoid putting several times the same source file name
	in the source list file.
	* prj-pp.adb (Print): Fix a bug in the placement of "at nn" for
	associative array indexes.

2009-11-30  Robert Dewar  <dewar@adacore.com>

	* g-dyntab.ads: Add missing pragma Compiler_Unit

2009-11-30  Thomas Quinot  <quinot@adacore.com>

	* s-crtrun.ads, s-crtl.ads, g-stseme.adb, Makefile.rtl, s-fileio.adb
	(System.CRTL.Runtime): New unit, to contain parts of s-crtl that are
	used in the Ada runtime but can't be used in the compiler because of
	bootstrap issues.
	* socket.c, s-oscons-tmplt.c, g-sothco.ads
	(System.OS_Constants.SIZEOF_struct_servent): New constant.
	Use s-oscons constant instead of external variable to get size of
	struct hostent.
