* gnat_ugn.texi: Generalize "finding memory problems" section into a
"memory management issues" section and document some of the useful
memory pools provided as part of the GNAT library.
Remove "virtual" from declaration of A::method2 in
the simple example of Ada/C++ mixed system.
Library Projects may be virtually extended: their virtual extensions
are not Library Projects.
Added section on extending project hierarchies.

2004-10-26 Thomas Quinot <quinot@act-europe.fr>
Ed Schonberg <schonberg@gnat.com>
* sem_util.adb (Is_Aliased_View): Defend against the case where this
subprogram is called with a parameter that is not an object name. This
situation arises for some cases of illegal code, which is diagnosed
later, and in this case it is wrong to call Is_Aliased, as that might
cause a compiler crash.
(Explain_Limited_Type): Refine previous fix to include
inherited components of derived types, to provide complete information.
* exp_ch9.adb (Set_Privals): Set the Ekind of the actual object that
is the prival for a protected object.
It is necessary to mark this entity as a variable, in addition to
flagging it as Aliased, because Sem_Util.Is_Aliased_View has been
modified to avoid checking the Aliased flag on entities that are not
objects. (Checking that flag for non-objects is erroneous and could
lead to a compiler crash).

(Convert_Array_Aggr_In_Allocator): New procedure to initialize the

Selectors are the GNAT.Sockets abstraction to perform a select()

select operation, some data is written to a dedicated socket that
is always monitored.
Under Windows, the write and read library functions cannot operate
on sockets, so we need to use send and recv instead, which is portable
across all supported platforms.
