+This document describes various features of IBM's Unix operating

+is compiled and/or runs.
=head2 Compiling Perl 5 on AIX
xlC.C 3.1.4.0
vac.C 4.4.0.3 (5.0 is already available)

+Perl can be compiled with either IBM's ANSI C compiler or with gcc.
+The former is recommended, as not only can it compile Perl with no
difficulty, but also can take advantage of features listed later that
require the use of IBM compiler-specific command-line flags.
Before installing the patches to the IBM C-compiler you need to know the
level of patching for the Operating System. IBM's command 'oslevel' will
-show the base, but is not allways complete:

4.3.0.0
AIX supports dynamically loadable libraries (shared libraries).
Shared libraries end with the suffix .a, which is a bit misleading,
-cause *all* libraries are shared ;-).
+because *all* libraries are shared ;-).
=head2 The IBM ANSI C Compiler
If you've chosen to use vac 4, be sure to run 4.4.0.3. Older versions
will turn up nasty later on.
+Here's a brief lead of how to upgrade the compiler to the latest
+level. Of course this is subject to changes. You can only upgrade
+versions from ftp-available updates if the first three digit groups
+are the same (in where you can skip intermediate unlike the patches
+in the developer snapshots of perl), or to one version up where the
+`base' is available. In other words, the AIX compiler patches are
+cumulative.
+
+ vac.C.4.4.0.1 => vac.C.4.4.0.3 is OK (vac.C.4.4.0.2 not needed)
+ xlC.C.3.1.3.3 => xlC.C.3.1.4.10 is NOT OK (xlC.C.3.1.4.0 is not available)
