* adaint.h, adaint.c: Add function __gnat_named_file_length
* impunit.adb: Add Ada.Directories to the list
* Makefile.in: Add VMS and Windows versions of
Ada.Directories.Validity package body.
* Makefile.rtl: Add a-direct and a-dirval
* mlib-tgt.ads: Minor comment update.
* a-dirval.ads, a-dirval.adb, 5vdirval.adb, 5wdirval.adb,
a-direct.ads, a-direct.adb: New files.

* make.adb (Scan_Make_Arg): Pass any -fxxx switches to gnatlink, not
just to the compiler.
2004-04-05 Robert Dewar <dewar@gnat.com>
* a-except.adb (Exception_Name_Simple): Make sure lower bound of
returned string is 1.
* ali-util.adb: Use proper specific form for Warnings (Off, entity)
* eval_fat.ads: Minor reformatting
* g-curexc.ads: Document that lower bound of returned string values
is always one.
* gnatlink.adb: Add ??? comment for previous change
(need to document why this is VMS specific)
* s-stoele.ads: Minor reformatting
* tbuild.ads: Minor reformatting throughout (new function specs)
* par-ch10.adb (P_Context_Clause): Handle comma instead of semicolon
after WITH.
* scng.adb: Minor reformatting
2004-04-05 Geert Bosch <bosch@gnat.com>
* eval_fat.adb (Machine): Remove unnecessary suppression of warning.
(Leading_Part): Still perform truncation to machine number if the
specified radix_digits is greater or equal to machine_mantissa.
2004-04-05 Javier Miranda <miranda@gnat.com>
* par-ch3.adb: Complete documentation of previous change
Correct wrong syntax documentation of the OBJECT_DECLARATION rule
(aliased must appear before constant).
* par-ch4.adb: Complete documentation of previous change.
* par-ch6.adb: Complete documentation of previous change.
* sinfo.ads: Fix typo in commment.
2004-04-05 Ed Schonberg <schonberg@gnat.com>
* sem_ch3.adb (Inherit_Components): If derived type is private and has
stored discriminants, use its discriminants to constrain parent type,
as is done for non-private derived record types.
* sem_ch4.adb (Remove_Abstract_Operations): New subprogram to implement
Ada 2005 AI-310: an abstract non-dispatching operation is not a
candidate interpretation in an overloaded call.
* tbuild.adb (Unchecked_Convert_To): Preserve conversion node if
expression is Null and target type is not an access type (e.g. a
non-private address type).
2004-04-05 Thomas Quinot <quinot@act-europe.fr>
* exp_ch6.adb (Rewrite_Function_Call): When rewriting an assignment
statement whose right-hand side is an inlined call, save a copy of the
original assignment subtree to preserve enough consistency for
Analyze_Assignment to proceed.
* sem_ch5.adb (Analyze_Assignment): Remove a costly copy of the
complete assignment subtree which is now unnecessary, as the expansion
of inlined call has been improved to preserve a consistent assignment
tree. Note_Possible_Modification must be called only
after checks have been applied, or else unnecessary checks will
be generated.
* sem_util.adb (Note_Possible_Modification): Reorganise the handling
of explicit dereferences that do not Come_From_Source:
- be selective on cases where we must go back to the dereferenced
pointer (an assignment to an implicit dereference must not be
recorded as modifying the pointer);
- do not rely on Original_Node being present (Analyze_Assignment
calls Note_Possible_Modification on a copied tree).
* sem_warn.adb (Check_References): When an unset reference to a pointer
that is never assigned is encountered, prefer '<pointer> may be null'
warning over '<pointer> is never assigned a value'.
2004-04-05 Ramon Fernandez <fernandez@gnat.com>
* tracebak.c: Change STOP_FRAME in ppc vxworks to be compliant with
the ABI.
2004-04-05 Olivier Hainque <hainque@act-europe.fr>
* 5gmastop.adb (Pop_Frame): Comment out the pragma Linker_Option for
libexc. We currently don't reference anything in this library and
linking it in triggers linker warnings we don't want to see.
* init.c: Update comments.
