INSTALL updates since _26

Here are my proposed updates to the INSTALL file.  Comments are welcome.
(I'd particularly welcome an AIX bos.* blurb from someone who understand
those things.)

It's not all that much, really; just some sections have been moved around
into what I hope is a more logical order.

+
+Configure distinguishes between the directory in which perl (and its

+
+Suppose you want to install perl under the F</tmp/perl5> directory.

+=head2 Configure-time Options
+
+There are several different ways to Configure and build perl for your
+system.  For most users, the defaults are sensible and will work.
+Some users, however, may wish to further customize perl.  Here are

+
+=head2 Binary Compatibility With Earlier Versions of Perl 5
+
+If you have dynamically loaded extensions that you built under
+perl 5.003 and that you wish to continue to use with perl 5.004, then you
+need to ensure that 5.004 remains binary compatible with 5.003.
+
+Starting with Perl 5.003, all functions in the Perl C source code have
+been protected by default by the prefix Perl_ (or perl_) so that you
+may link with third-party libraries without fear of namespace
+collisions.  This change broke compatibility with version 5.002, so
+installing 5.003 or 5.004 over 5.002 or earlier will force you to
+re-build and install all of your dynamically loadable extensions.
+(The standard extensions supplied with Perl are handled
+automatically).  You can turn off this namespace protection by adding
+-DNO_EMBED to your ccflags variable in config.sh.
+
+Perl 5.003's namespace protection was incomplete, but this has
+been fixed in 5.004.  However, some sites may need to maintain
+complete binary compatibility with Perl 5.003.  If you are building
+Perl for such a site, then when B<Configure> asks if you want binary
+compatibility, answer "y".
+
+On the other hand, if you are embedding perl into another application
+and want the maximum namespace protection, then you probably ought to
+answer "n" when B<Configure> asks if you want binary compatibility.
+
+The default answer of "y" to maintain binary compatibility is probably
+appropriate for almost everyone.
