* g-socket.adb (Abort_Selector): Initialize Buf to prevent valgrind
from complaining on potential uninitialized reference.
Change calls to GNAT.Sockets.Thin.Is_Socket_In_Set to account for
new specification and test explicitly for non-zero return value.
* g-socthi.ads (Is_Socket_In_Set): Declare imported function as
returning C.int, to avoid using a derived boolean type.
* exp_ch5.adb (Make_Tag_Ctrl_Assignments): Use
Duplicate_Subexpr_No_Checks in preference to direct use of
Remove_Side_Effects and New_Copy_Tree.
Clear Comes_From_Source on prefix of 'Size attribute reference.
* g-socthi.adb, g-socthi-vms.adb, g-socthi-mingw.adb,
g-socthi-vxworks.adb: Change calls to
GNAT.Sockets.Thin.Is_Socket_In_Set to account for new specification
and test explicitly for non-zero return value.
* g-socthi-vms.ads, g-socthi-mingw.ads, g-socthi-vxworks.ads:
(Is_Socket_In_Set): Declare imported function as returning C.int, to
avoid using a derived boolean type.

* decl.c (gnat_to_gnu_entity) <E_Array_Subtype>: Adjust condition to
ignore overflows on low and high bounds of an index to also account for
differences in signedness between sizetype and gnu_index_subtype.
These are as legitimate as the ones caused by a lower TYPE_PRECISION
on sizetype.
2004-08-09 Robert Dewar <dewar@gnat.com>
* s-solita.ads, s-solita.adb: Minor reformatting
* gnat_rm.texi: Add documentation for pragma Profile (Restricted)

* vms_conv.ads: Minor reformatting
* s-secsta.adb: Use SS_Ptr instead of Mark_Id as stack pointer (cleanup
and necessary for following change).

* s-secsta.ads: Define SS_Ptr to be used instead of Mark_Id as stack
pointer (cleanup and necessary for following change).

statements mustbe inserted before the select itself.
* sem_attr.adb (Analyze_Attribute, case 'Size): Handle properly the

elsewhere.

composite equality.

expressions of Unchecked_Union type. Check the body of subprogram for

Component_Is_Unconstrained_UU. It is used to detect whether a single
component is of an unconstrained Unchecked_Union subtype. Add function
Variant_Is_Unconstrained_UU. It is used to detect whether a single

Unchecked_Union. Add procedure Check_Component. It is used to inspect
per-object constrained components of Unchecked_Unions for being
Unchecked_Unions themselves. Add procedure Check_Variant. It is used to
check individual components withing a variant.
