Change 31950 by merijnmerijn-nb09 on 2007/09/24 08:34:14

        Announce plans for -Duse32bit* options for
Configure, and document
        that there is no guarantee on 32bit builds when no
args passed

 aware.

 Natively 64-bit systems need neither -Duse64bitint nor
-Duse64bitall.
+On these systems, it might be the default compilation mode,
and there
+is currently no guarantee that passing no use64bitall
option to the
+Configure process will build a 32bit perl. Implementing
-Duse32bit*
+options is planned for perl 5.12.
