* lib-load.adb (Make_Instance_Unit): In the case where In_Main is

2009-04-24  Emmanuel Briot  <briot@adacore.com>

* prj-proc.adb, prj-nmsc.adb (Find_Ada_Sources,

basically doing the same work (for explicit or implicit sources).
(Find_Explicit_Sources): renamed to Find_Sources to better reflect its
role. Rewritten to share some code (testing that all explicit sources

* prj-proc.adb, make.adb, mlib-prj.adb, prj.adb, prj.ads, makeutl.adb,
clean.adb, prj-nmsc.adb, prj-env.adb, prj-env.ads (Project_Data.Seen):
field removed. This is not a property of the
project, just a boolean used to traverse the project tree, and storing
it in the structure prevents doing multiple traversal in parallel.
(Project_Data.Checked): also removed, since it was playing the same role
as Seen when we had two nested loops, and this is no longer necessary
(For_All_Imported_Projects): removed, since in fact there was already
the equivalent in For_Every_Project_Imported. The latter was rewritten
to use a local hash table instead of Project_Data.Seen
Various loops were rewritten to use For_Every_Project_Imported, thus
removing the need for Project_Data.Seen. This avoids a lot of code
duplication

* sem_res.adb (Resolve_Actuals): Do not create blocks around code
statements, even though the actual of the call is a concatenation,
because the argument is static, and we want to preserve warning
messages  about sequences of code statements that are not marked
volatile.

* sem_warn.adb: remove obsolete comment about warning being obsolete

* s-tasren.adb (Task_Do_Or_Queue): If a timed entry call is being
requeued and the delay has expired while within the accept statement
that executes the requeue, do not perform the requeue and indicate that
the timed call has been aborted.
