    • re PR ada/12806 (Program_Error sinput.adb:397) · 12e0c41c 
      	* sysdep.c: Problem discovered during IA64 VMS port.
	[VMS] #include <unixio.h> to get proper prototypes.

	* adaint.c:
	Issues discovered/problems fixed during IA64 VMS port.
	[VMS] #define _POSIX_EXIT for proper semantics.
	[VMS] #include <unixio.h> for proper prototypes.
	[VMS] (fork): #define IA64 version.
	(__gnat_os_exit): Remove unnecessary VMS specific code.

	* 3vtrasym.adb: Minor reformatting
	Use terminology encoded/decoded name, rather than C++ specific notion
	of mangling (this is the terminology used throughout GNAT).

	* einfo.h: Regenerated

	* einfo.ads, einfo.adb: Add new flag Is_Thread_Body

	* exp_ch6.adb:
	(Expand_N_Subprogram_Body): Handle expansion of thread body procedure

	* par-prag.adb: Add dummy entry for Thread_Body pragma

	* rtsfind.ads:
	Add entries for System.Threads entities for thread body processing

	* sem_attr.adb:
	(Analyze_Pragma, Access attributes): Check these are not applied to a
	thread body, since this is not permitted

	* sem_prag.adb: Add processing for Thread_Body pragma.
	Minor comment fix.

	* sem_res.adb:
	(Resolve_Call): Check for incorrect attempt to call a thread body
	 procedure with a direct call.

	* snames.ads, snames.adb: Add entry for Thread_Body pragma
	Add names associated with thread body expansion

	* snames.h: Add entry for Thread_Body pragma

	Remove trailing blanks and other style errors introduced in previous
	change.

	* decl.c (gnat_to_gnu_field): Adjust the conditions under which we get
	rid of the wrapper for a LJM type, ensuring we don't do that if the
	field is addressable.  This avoids potential low level type view
	mismatches later on, for instance in a by-reference argument passing
	process.

	* decl.c (gnat_to_gnu_field): No longer check for BLKmode being
	aligned at byte boundary.

	linking).
