When compiling Perl, you must use an ANSI C compiler. AIX does not ship
an ANSI compliant C-compiler with AIX by default, but binary builds of

=head2 64-bit Perl
If your AIX system is installed with 64-bit support, you can expect 64-bit
configurations to work. If you want to use 64-bit Perl on AIX 6.1
you need a APAR for a libc.a bug which affects (n)dbm_XXX functions.
-The APAR number for this problem is currently not yet available. If
-the fileset bos.rte.libc is at level 6.1.1.2 or lower then the problem

If you need more memory (larger data segment) for your Perl programs you

AIX supports dynamically loadable objects as well as shared libraries.
Shared libraries by convention end with the suffix .a, which is a bit
misleading, as an archive can contain static as well as dynamic members.
