re PR ada/12806 (Program_Error sinput.adb:397)

	* 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

	* s-thread.adb: Add entries for thread body processing
	These are dummy bodies so far

	* s-thread.ads: Add documentation on thread body handling.
	Add entries for thread body processing.

	* sem_ch10.adb:
	(Build_Limited_Views): Return after posting an error in case of limited
	with_clause on subprograms, generics, instances or generic renamings
	(Install_Limited_Withed_Unit): Do nothing in case of limited with_clause
	on subprograms, generics, instances or generic renamings

	* raise.c (setup_to_install): Correct mistake in last revision; two
	arguments out of order.

	* trans.c, cuintp.c, argv.c, aux-io.c, cal.c, errno.c, exit.c,
	gnatbl.c, init.c, stringt.h, utils.c, utils2.c: Update copyright
	notice, missed in previous change.
	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.

	* decl.c (components_to_record): Do not delete the empty variants from
	the end of the union type.

	* exp_ch4.adb (Expand_N_Op_Eq): Use base type when locating primitive
	operation for a derived type, an explicit declaration may use a local
	subtype of Boolean.

	* make.adb (Gnatmake): Allow main sources on the command line with a
	library project when it is only for compilation (no binding or
	linking).

	Part of PR ada/12806:

	* ada-tree.h (TYPE_DIGITS_VALUE, SET_TYPE_DIGITS_VALUE): Save count as
	tree, not integer.

	* decl.c:
	(gnat_to_gnu_entity, case E_Floating_Point_Type): Save count as tree,
	not integer.

	* targtyps.c, decl.c, misc.c,
	gigi.h (fp_prec_to_size, fp_size_to_prec): Temporary
	routines to work around change in FP sizing semantics in GCC.

	* utils.c:
	(build_vms_descriptor): TYPE_DIGITS_VALUE is tree, not integer.

	* gigi.h: (enumerate_modes): New function.

	* Make-lang.in: (ada/misc.o): Add real.h.

	* misc.c: (enumerate_modes): New function.
