* a-calend-vms.adb (Leap_Sec_Ops): Temp body for package in private
part of Ada.Calendar: all subprogram raise Unimplemented.
(Split_W_Offset): Temp function body, raising Unimplemented
* a-calend.ads, a-calend-vms.ads:
Add imported variable Invalid_TZ_Offset used to designate targets unable
to support time zones.
(Unimplemented): Temporary function raised by the body of new
subprograms below.
(Leap_Sec_Ops): New package in the private part of Ada.Calendar. This
unit provides handling of leap seconds and is used by the new Ada 2005
packages Ada.Calendar.Arithmetic and Ada.Calendar.Formatting.
(Split_W_Offset): Identical spec to that of Ada.Calendar.Split. This
version returns an extra value which is the offset to UTC.
* a-calend.adb (Split_W_Offset): Add call to localtime_tzoff.
(Leap_Sec_Ops): New body for package in private part of Ada.Calendar.
(Split_W_Offset): New function body.
(Time_Of): When a date is close to UNIX epoch, compute the time for
that date plus one day (that amount is later substracted after
executing mktime) so there are no problems with time zone adjustments.
* a-calend-mingw.adb: Remove Windows specific version no longer needed.
* a-calari.ads, a-calari.adb, a-calfor.ads, a-calfor.adb,
a-catizo.ads, a-catizo.adb: New files.
* impunit.adb: Add new Ada 2005 entries
* sysdep.c: Add external variable __gnat_invalid_tz_offset.
Rename all occurences of "__gnat_localtime_r" to
"__gnat_localtime_tzoff".
(__gnat_localtime_tzoff for Windows): Add logic to retrieve the time
zone data and calculate the GMT offset.
(__gnat_localtime_tzoff for Darwin, Free BSD, Linux, Lynx and Tru64):
Use the field "tm_gmtoff" to extract the GMT offset.
(__gnat_localtime_tzoff for AIX, HPUX, SGI Irix and Sun Solaris): Use
the external variable "timezone" to calculate the GMT offset.

* sem_res.adb (Resolve_Unary_Op): Add warning for use of unary minus
with multiplying operator.
(Expected_Type_Is_Any_Real): New function to determine from the Parent
pointer whether the context expects "any real type".
(Resolve_Arithmetic_Op): Do not give an error on calls to the
universal_fixed "*" and "/" operators when they are used in a context
that expects any real type. Also set the type of the node to
Universal_Real in this case, because downstream processing requires it
(mainly static expression evaluation).
Reword some continuation messages
Add some \\ sequences to continuation messages
(Resolve_Call): Refine infinite recursion case. The test has been
sharpened to eliminate some false positives.
Check for Current_Task usage now includes entry barrier, and is now a
warning, not an error.
(Resolve): If the call is ambiguous, indicate whether an interpretation
is an inherited operation.
(Check_Aggr): When resolving aggregates, skip associations with a box,
which are priori correct, and will be replaced by an actual default
expression in the course of expansion.
(Resolve_Type_Conversion): Add missing support for conversion from
a class-wide interface to a tagged type. Minor code cleanup.
(Valid_Tagged_Converion): Add support for abstact interface type
conversions.
(Resolve_Selected_Component): Call Generate_Reference here rather than
during analysis, and use May_Be_Lvalue to distinguish read/write.
(Valid_Array_Conversion): New procedure, abstracted from
Valid_Conversion, to incorporate accessibility checks for arrays of
anonymous access types.
(Valid_Conversion): For a conversion to a numeric type occurring in an
instance or inlined body, no need to check that the operand type is
numeric, since this has been checked during analysis of the template.
Remove legacy test for scope name Unchecked_Conversion.
* sem_res.ads: Minor reformatting
* a-except.adb, a-except-2005.adb: Turn off subprogram ordering
(PE_Current_Task_In_Entry_Body): New exception code
(SE_Restriction_Violation): Removed, not used
* a-except.ads: Update comments.
* types.h, types.ads: Add definition for Validity_Check
