	* g-sha256.ads, s-sehamd.ads, s-sehamd.adb, g-sha512.ads, g-sha224.ads,
	g-sha384.ads: Minor reformatting

2009-11-30  Emmanuel Briot  <briot@adacore.com>

	* adaint.h (file_attributes): Reduce size of the structure, so that it
	is less costly to store in records.
	* makeutl.adb:
	(Check_Source_Info_In_ALI): use Full_Source_Name instead of a direct
	call to Find_File, since the former provides caching when appropriate,
	which limits the number of system calls in some cases.
	* osint.ads, prj.ads (Source_Data): do not store directly the timestamp,
	but the file attributes since we also need access to the size of the
	ALI file to parse it. This gives an opportunity for saving system calls
	on Unix systems.
