=head1 SYNOPSIS
This constant is set to 1 if your kernel supports the three extended fields C<totalhigh>, C<freehigh> and C<mem_unit> ; and to 0 otherwise.
+=head1 BINARY COMPATIBILITY
+
+If you upgrade your kernel to a greater version than 2.3.23 on i386 or 2.3.48 on any other platform, you will need to rebuild the module to access the extended fields.
+
+Moreover, since the perl hash function has changed after the 5.6 version, you will also need to recompile the module if you upgrade your perl from a version earlier than 5.6.
